denis23 [38]

Answer:

The radius of the sphere, to the nearest cm:

$r\approx 20$ cm

Step-by-step explanation:

The surface area of a sphere is given by the formula

A = 4πr²

where r is the radius of the sphere.

Given

The surface area of sphere A = 5024 cm²

The radius of the sphere can be determined such as

$A\:=\:4\pi r^2$

$r\:=\:\frac{1}{2}\sqrt{\frac{A}{\pi }}$

Plug in Surface Area of sphere = 5024, π = 3.14 in the formula

$\:r\:=\:\frac{1}{2}\sqrt{\frac{5024}{3.14}}\:\:$

$r\approx 20$ cm

Therefore, the radius of the sphere, to the nearest cm:

$r\approx 20$ cm
