Question

What is the volume and total surface area of a sphere with the radius 2.25in?

Answer 1

The volume is 15.89625

Answer 2

Answer:

Step-by-step explanation:

The formula for determining the volume of a sphere is expressed as

Volume = (4/3)πr³

Where

r represents the radius of the sphere.

π is a constant whose value is 3.14

From the information given,

radius = 2.25 inches

Volume = 4/3 × 3.14 × 2.25³

Volume = 47.69 inches³

The formula for determining the total surface area of a sphere is expressed as

Total surface area = 4πr²

Therefore

Total surface area = 4 × 3.14 × 2.25²

= 63.9 inches²
