# Surface Area of Spheres and Hemispheres Worksheets

The total area that the surface of the sphere or hemisphere occupies is what grade 7, grade 8, and high school students are expected to determine in these printable worksheets. The sphere, with no flat surfaces has the formula 4πr^{2}. However, for the hemisphere, with a curved and a flat surface, we find the TSA, which is the sum of the CSA (half the surface area of a sphere) 2πr^{2} + area of the flat face: circle 2πr^{2}; making it 3πr^{2}. The trick, is to memorize the formula and use it appropriately. To do this effortlessly we have included a variety of exercises with dimensions presented as integers and decimals. Our free worksheets must be your pick to initiate practice.

Surface Area of Spheres and Hemispheres | Integers - Easy
