Question

What is the area of a circle with a diameter of 16.2 in.? Use 3.14 for pi and round your final answer to the nearest hundredth

Answer 1

A ≈ 206.02 in²

Explanation:

the area (A) of a circle is calculated as

A = πr² ( r is the radius )

given diameter = 16.2 in , then r = 16.2 ÷ 2 = 8.1 in

using 3.14 for π , then

A = 3.14 × 8.1² = 3.14 × 65.61 ≈ 206.02 in² ( to the nearest hundredth )
