Question

if the surface area of a sphere is 100 pie square.cm, then find its radius​

Answer 1

Step-by-step explanation:

given the surface area of the sphere = 100πcm^2

formula for the surface area of a sphere is 4πr^2

⇒ 4πr^2 = 100πcm^2

⇒ 4r^2 = 100π/π

⇒ 4r^2 = 100

⇒ r^2 = 100/4

⇒ r^2 = 25

⇒ r = √25

⇒ r = 5

hence the radius of the sphere is 5cm.

i hope this helps you
