Answer 1

he lateral surface area of the cylinder is 2πrh where h=2r .

Lateral Surface Area of the Cylinder =2πr(2r)=4πr2 .

Therefore, the Surface Area of a Sphere with radius r equals 4πr2 .

Example :

Find the surface area of a sphere with radius 5 inches.

S.A.=4π(5)2=100π inches2≈314.16 inches2
