The surface area of a sphere depends on its radius, so the area is a function of the radius. If this function is called A(r), use the formula below to compute
A(5), the area of a sphere with a radius of 5 units.
A(r) = 4pier²

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
