Question

Find the area and the circumference of a circle with radius 7 m.

Use the value 3.14 for π, and do not round your answers.

Area=?
Circumference=?

Answer 1

`Area = 153.938040026m^2`

`Circumference= 43.9822971503m`

Explanation:

Area

`Area = \pi r^2\\Area = \pi *7^2\\Area = 49\pi\\Area = 153.938040026`

Circumference

`C = 2\pi r\\C = 2\pi*7\\C= 14\pi\\C=43.9822971503`
