The equation for the surface area of a sphere is 4∏R2

Insert values for r

4x(pi)x32

4x(pi)x9

4x9=36pi

36xpi = 133.076 units2

Surface area of a sphere = 4 (pi)r2For a sphere of radius 3,

A = 4 (3.14159)(32)

A = (4)(3.14159)(9) = 113.097

A = about 113.1 square units

What is the surface area of a cylinder with end that are half sphere with a radius of 4 and height of 12?

If the radius of the hemispheres is 4, then that leave 4 units for the length if the straight part of the cylinder. Total surface area = surface area of 1/2 sphere of radius 4 + lateral surface area of cylinder of radius 4 and height 4 + surface area of 1/2 sphere of radius 4. = surface area of sphere of radius 4 + lateral surface area of cylinder of radius 4 = 4*3*pi*43 + pi*42*4 = 469.1 cubic units.
