Question

What is the area of a circle with diameter of 13 to the nearest tenth? (Use 3.14 for π.)

Answer 1

132.7

Explanation:

Area of circle = π · r²

Radius = 1/2 of diameter

Radius = 6.5

Let's solve

Area of circle = 3.14 · 6.5²

= 3.14 · 42.25

= 132.665

= 132.7

So, the area of the circle is 132.7
