Answer 1

The answer is 38.5 m2

Answer 2

The answer is 38.5 m²

Explanation:

To find the are of a circle you use A=3.14×r².

The diameter is 7 so the radius is 3.5. 3.5×3.5 is 12.25. Then, you multiply pi by the radius squared which is 3.14×12.25=38.465. Rounding to the nearest tenth gives you 38.5m².
