Question

If the surface area of a sphere is 100π cm2 what is the radius

Answer 1

Answer: 5cm

Step-by-step explanation:

surface area of sphere= 4 pi (radius)^2

then, 100picm^2= 4pi r^2

r=5cm

Answer 2

ANSWER:------

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.
