Question

Find the area of a circle with a diameter of 6.

Either enter an exact answer in terms of 7 or use 3.14 for T and enter your answer as a decimal.

Answer 1

Answer: 28.26

Explanation:

Formula :
`A = \pi*r^2`

`r = (d)/(2)`

`r=(6)/(2)`

`r = 3`

`A = \pi*(3)^2`

`A = \pi*9`

`A =9\pi`

or

`A =9(3.14)`

`A=28.26`
