Question

I need help bad only with the first 2

Answer 1

Circumference: 12.56 m

Area: 452.16 m²

Explanation:

Circumference:

2 × 3.14 × 12

12.56 m

Area:

3.14 × 12²

452.16 m²

Answer 2

C =75.36 m

A =452.16 m^2

Explanation:

The circumference is found by where r is the radius and pi = 3.14

C = 2 * pi *r

C = 2 * 3.14 * 12

C =75.36 m

The area is found by

A = pi r^2

A = 3.14 * 12^2

A =452.16 m^2
