Question

Find the circumference

and the area of a circle with radius 9 m.
Use the value 3.14 for and do not round your answers. Be sure to include the correct units in your answers.

Answer 1

56.52m is the circumference. The area is 254.34
`m^(2)`

Explanation:

The equation for the circumference of a circle is c=2πr with r being the radius. So 2(3.14)(9)=56.52m. The area equation for a circle is A=π
`r^(2)` so it would be (3.14)(9)^2 or (3.14)(81) which equals 254.34
`m^(2)`
