Step-by-step explanation:

2. The radius of the sphere is 5.04 cm rounded to the nearest centimeter.

### What is Surface Area?

Surface Area is the total area of the outer surface of a three-dimensional figure.
A sphere is a geometrical object that is analogous to a circle, all the points of the sphere are at the same distance from the center of the sphere.
The surface area of a sphere is 320 square centimeters.
The radius of the sphere has to be determined,
The surface area of the sphere is given by,
A = 4 π r²
Substituting the values of A in the formula,
320 = 4 π r²
320 = 4 * 22* r² / 7
320 * 7 /( 4*22) =  r²
r² = 2240/88
r²  = 280/11
r = 5.045 cm
The radius of the sphere is 5.045 cm.
