Question

? Find the radius and area of a circle with a circumference of 43.96. Round your answer to the nearest tenth. Use 3.14 for Radius = Area =

Answer 1

The equation for the circunference of the circle is

`L=2\pi r`
`r=(L)/(2\pi)=(43.96)/(2\cdot3.14)`
`r=7`

Area

`A=\pi r^2`
`A=3.14\cdot7^2`
`A=3.14\cdot49`
`A=153.86`

Radius is 7

Area is 153.86
