Question

A circle's diameter is 12 yards. What is the circle's area?

Use 3.14 for pi and provide an answer accurate to the nearest tenth.

Answer 1

113.1

Explanation:

The way to find the circle's area is A=πr^2:

The radius is diameter/2, so the radius is 12/2, which is 6

Therefore, A=3.14*6^2 ≈ 113.09734

Now to round to the nearest tenth, it would be 113.1, the final answer.
