Question

Find the area of a circle with radius of 9

Answer 1

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}$

Answer 2

Answer:

The area of the circle would be 254.47
