Answer:
1. 706.5ft²
2. 69.08in²
3. 275.4yd²
4. 37.68yd²
5. 28.26in²
6. 106.76ft²
Step-by-step explanation:
1.
A= πr²
A= 3.14 (15ft × 15ft)
A= 3.14 × 225ft²
A=706.5ft²
2.
A= πd
A= 3.14 × 22in
A= 69.08in²
3.
A= πr²
A= 3.14 (9yd × 9yd)
A= 3.14 × 81yd²
A= 275.4yd²
4.
A= πd
A= 3.14 × 12yd
A= 37.68yd²
5.
A= πr²
A= 3.14 (3in × 3in)
A= 3.14 × 9in²
A= 28.26in²
6.
A= πd
A= 3.14 × 34ft
A= 106.76ft²
hope it helps
