Answer:
The radius of the sphere, to the nearest cm:
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


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

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