Volume of Rectangular pyramids | Unit conversion
Convert the given dimensions to one unit, find the area of the rectangular base, and multiply it with 1/3rd of the pyramid's height.
Surface Area of Square Pyramids
Multiply the slant height of the pyramid with half the perimeter of the square base. Add this up with the base area for the surface area.
Volume of Cones | Using the Slant Height of the Cone
Apply the Pythagorean theorem; find out the missing radius(r) or height(h); substitute the measures in the formula V = 1/3 πr2h.
Surface Area of a Cone | Finding the Missing Measure
Plug the known measures in SA = πr (l + r) and solve for the radius of slant height. Replace 'l' by √(h2 + r2) for the unknown height.
Volume of Cylinders | Missing parameter
Either radius/diameter or height of the cylinder and its volume are given. Substitute them in the formula and find the other parameter.
Surface Area of Cylinders - Decimals
Print this practice set and calculate the surface area of cylinders whose attributes are rendered in decimals.
Volume of Spheres and Hemispheres
The radius or diameter of the spheres and hemispheres are offered as integers. Determine their volumes using the appropriate formula.
Surface Area of Spheres and Hemispheres
Recall these: SA of a sphere is 4πr2 and SA of a hemisphere is 3πr2, and solve the problems here.
Use the relevant formulas and determine the volume of triangular and rectangular pyramids and right cones with decimal dimensions.
Surface Area of Mixed Shapes | Fractional Lengths
Compute the surface areas of spheres, hemispheres, pyramids, prisms, cones, and cylinders with fractional measures.
Volume of Composite Figures | Adding 2 or 3 Solid Shapes
The figures are composed of 2 or 3 solid shapes. Figure out the volumes of each solid and add them up for the total volume.
Surface Area of Circumscribed Figures | Solids within Solids
Subtract the base areas of inner solid from the sum of SA of the outer solid and SA of the part within (inner solid's lateral area).
