The area of the circle would be 254.47

Hope this helps!!

Answer 2

The formula for the area of a circle is Area =
`\pi`
`r^(2)`

Since the radius of the circle is 9 cm, we can plug 9 cm in for the radius in our formula. Now we have

`\pi` (9 cm)
`^(2)`. Remember that 9 cm
`^(2)` is the same thing as 9 cm × 9 cm.

`\pi` (9 cm) (9 cm) = 81
`\pi`
`cm^(2)`
