Answer:

The answer is 44.0 m

Step-by-step explanation:

The circumference of a circle = 2πr

where

r is the radius of the circle

From the question

r = 7 m

Substitute this value into the above formula and solve

That's

C = 2(7)π

= 14π

= 43.9822971502

We have the final answer as

44.0 m to the nearest tenth

Hope this helps you

Circumference formula: C = 2πr

C = 2π(7)

C = 14π

C ≈ 43.98

Area formula: A = πr²

A = π(7)²

A = 49π

A ≈ 153.94

Best of Luck!
