Circles Worksheets

Plenty of free circle worksheets are provided for kids to develop their knowledge and skills in finding area and circumference of a circle, finding area of a sector, arc length, perimeter of sector, chord, tangent, secant, concentric circles and more.

Special focus in circle worksheets:

Area of Circle Worksheets

Circumference of Circle Worksheets

Basic Circles Worksheets:

Coloring activities and identifying parts of circle are provided for beginners. Student can print the parts of a circle and paste it at home or in classroom.

 Color the circles Identify the center, radius and diameter

Diameter is the longest chord in a circle and radius is half the diameter. Take radius and diameter worksheets to understand them clearly.

 Find radius from diameter Find diameter from radius

Parts of Circle Worksheets:

These worksheets are suitable for middle and high school students. Identifying center, radius, diameter, chord, secant, tangent, minor and major segments, minor and major arcs and more.

Area of Circle Worksheets

Area of a circle = pi * r^2, where r is the radius. pi = 22/7 or 3.14 (rounded to nearest hundredth). Sometimes area will be rounded at the final answer. Lots and lots of area of circle worksheets are given here with all possible combinations. Worksheets based on finding the area using radius or diameter or circumference; finding the radius or diameter or circumference using area is provided for practice.

Using the formula given above, you can find the area of a circle using radius. These are the basic worksheets in area of circle.

 Find area using radius-1 Find area using radius-2

Area Using Diameter:

Find the radius and then apply the area of a circle formula. Otherwise, you can apply A = pi * (d^2/4) to find the area, where d is the diameter.

 Find area using diameter-1 Find area using diameter-2

Find Radius Using Area:

Area of a circle will be given and radius has to be found. You may need to take the square root. Little hard but worth to try.

 Find radius using area-1 Find radius using area-2

Find Diameter Using Area:

Once you are familiar with finding radius from area, then finding diameter is very simple. Find the radius and just double it.

 Find diameter using area-1 Find diameter using area-2

Combination of radius and diameter for circles are given. Use the proper formula to find the area of a circle.

Find Radius/Diameter Using Area:

You may need to find the radius or diameter from area of a circle. Highly improve your arithmetic and geometric skill in calculation and understanding.

Find Area Using Circumference:

Little hard and complicate area worksheets for kids who look for hard worksheets. Find the radius from the circumference and then find the area. Yes, it is that simple but challenging calculations.

Circumference of Circle Worksheets

Perimeter or Circumference of a circle = 2 * pi * r, where r is the radius. pi = 22/7 or 3.14 (rounded to nearest hundredth). As in area worksheets, answers to be rounded off to the required place values. Circumference worksheets are based on finding the circumference using radius or diameter or area; finding the radius or diameter or area from circumference are provided to drill your skills on circle.

Find the circumference of a circle for the given radius by using the formula given above.

 Find circumference using radius-1 Find circumference using radius-2

Circumference Using Diameter:

Circumference = pi * d. Use this formula to find the circumference when diameter is given.

 Find circumference using diameter-1 Find circumference using diameter-2

Find Radius Using Circumference:

Problems become simple if the circumference is given in terms of pi. Otherwise you should work out to find the radius.

 Find radius using circumference-1 Find radius using circumference-2

Find Diameter Using Circumference:

Divide the circumference by pi to find the diameter of a circle. Problems are easy if the circumferences are in terms of pi.

 Find diameter given circumference-1 Find diameter using circumference-2

Find Circumference Using Radius/Diameter:

Decide the correct formula to find the circumference as you gonna get both radius and diameter in these worksheets. Formula is not really big. So no worries. :-)

Find Radius/Diameter Using Circumference:

Divide the circumference by 2pi when the radius is given or divide by pi when the diameter is given. Burden will be less if the circumferences are in terms of pi.

Find Circumference Using Area:

These worksheets are little hard and challenging. You may need a help of calculator to do few problems.

 Find circumference using area-1 Find circumference using area-2

Sector of a Circle Worksheets

Sector is part of the circle. Given below are the worksheets to find the area of sector, perimeter of sector and finding length of the arc. Round the answers to the nearest hundredth wherever necessary. These worksheets are suitable for grade 6 and up kids.

Area of Sector Worksheets:

Worksheets include finding the area of sectors using the degree, radians and arc length. It is important to know the formula to solve these worksheets.

 Area using degree Area using radians Area using arc length

Perimeter of Sector Worksheets:

We can find the perimeter using the central and angle or using radius and arc length. Suitable for grade 6 and up kids

 Perimeter using degree Perimeter using arc length

Length of the Arc Worksheets:

Use suitable formula to find the length of the arc using degree and radians.

 Arc length using degree Arc length using radians
