Answer 2

Answer:

1. Circumference = 25 1/7cm Area = 201 1/7 cm^2

2. Circumference = 31 3/7cm Area = 314 2/7 cm^2

3. Circumference = 33cm Area = 707 1/7 cm^2

Step-by-step explanation:

1. 8 * (22/7)

Circumference = 25 1/7cm

8 * 8 * (22/7)

Area = 201 1/7 cm^2

2. 10 * (22/7)

Circumference = 31 3/7cm

10 * 10 * (22/7)

Area = 314 2/7 cm^2

3. 15 * (22/7)

Circumference = 33cm

15 * 15 * (22/7)

Area = 707 1/7 cm^2
