Gain mastery in finding the volume of cones using this batch of printable math worksheets. Plug the given radius(r) and height(h) in the formula V = 1/3πr2h and find the volume of the cone.
Add up the areas of the curved part and the base of the cones to figure out their surface area.
Use the formula V = πr2h, where r is the radius and 'h' the height of the cylinder and calculate the volume.
Surface Area of Cylinders - Fractions
Determine the areas of the rectangular face and two circular bases and sum them up for the SA of a cylinder.
Calculate the volume of the spheres by replacing r with the given radius and π with 3.14 in the formula, V = 4/3πr3.
Surface Area of Spheres and Hemispheres | Missing Parameter
Equate the given surface area of spheres to 4πr2 and hemispheres to 3πr2 and derive their diameter or radius as directed.
Volume of Prisms and Cylinders
Recap volume as the area of base multiplied by height/length and figure it out for the rectangular and triangular prisms and cylinders.
Surface Area of Prisms and Cylinders
Visualize the net of each solid figure; add the areas of their faces and bases; work out the surface area.
Volume of Composite Figures | Adding 2 Solid Shapes
Decompose each compound figure into two disjoint figures, find the individual volumes, and add them.
Surface Area of Composite Figures | Cones, Cylinders, and Hemispheres
Compute the surface areas of the cones, cylinders, and hemispheres that make up the compound figure, and add them.
Mixed Pyramids | Volume of Pyramids | Missing Measure
Substitute the known measures in the appropriate formula for the volume of pyramids, isolate the unknown, and solve.
Surface Area of Regular Polygonal Pyramids
The areas of the triangular faces and polygonal bases together will give you the surface area of the pyramids here.
Volume of the Shaded Region | Subtracting Solid Shapes
Into a solid lie one or more smaller solids. Subtract the volume of the smaller ones from the larger to find the volume of the shaded region.
Surface Area of Mixed Shapes - Integers
Apply the appropriate formulas, substitute the integer dimensions, and determine the surface areas of a variety of 3D shapes.
Volume of Mixed Shapes - Decimals
Find the volume of prisms, pyramids, spheres, hemispheres, cones, and cylinders with decimal measures using relevant formulas.
