Answer:

the surface area of a sphere with a radius of 5 cm is 314 cm^2

Explanation:

the surface area of a sphere with a radius of 5 cm

Surface area of a sphere formula =
$4\pi r^2$

where 'r' is the radius of the sphere

r= 5cm

Surface area of a sphere =
$4\pi (5)^2$

The value of pi = 3.14

Surface area of a sphere =4*3.14 * 25 = 314

the surface area of a sphere with a radius of 5 cm is 314 cm^2
