Any help will be appreciated thank you!

Answer 1

1. 232.35 cm²

2. 52.81 cm²

3. 373.25 cm²

Explanation:

1. Area of circle = πr²

radius (r) = 8.6

Area = π*8.6²

Area = 232.35 cm²

2. Area of circle = πr²

radius (r) = 4.1 cm

Area = π*4.1²

Area = 52.81 cm²

3. Area of circle = πr²

radius (r) = 10.9 cm

Area = π*10.9²

Area = 373.25 cm²
