Question

10 POINTS
Find the area of each circle. Round to the nearest tenth.

Answer 1

84.9

Explanation:

10.4/2= 5.2

5.2x5.2x22/7= 84.9820..

Answer 2

84.9 yd²

Explanation:

The area (A) of a circle is calculated as

A = πr² ← r is the radius

here diameter = 10.4, hence r = 10.4 ÷ 2 = 5.2, thus

A = π × 5.2² = 27.04π ≈ 84.9 yd² ( to the nearest tenth )
