Soccer balls come in several different sizes. One of the soccer balls has a diameter of 9 inches. What is the surface area of this soccer ball? Round your answer to the nearest tenth.

Respuesta :

Answer: 254.3 inches²

Step-by-step explanation:

The shape of a soccer ball is a sphere. The formula for calculating surface area of a sphere= 4πr²

Since diameter= 9 inches

Radius = Diameter/2 = 9/2

Radius = 4.5 inches

π = 3.14

Surface area= 4πr²

= 4 × 3.14 × 4.5²

= 4 × 3.14 × 4.5 × 4.5

= 254.3 inches²
