Question

The radius of a circle is 9 inches. What is the circle's area? Use 3.14 for ​.

Answer 1

Answer:

254.34 in²

Step-by-step explanation:

Area of a circle

• A = πr²

1. r = radius of the circle

Solving

• A = 3.14 x (9)²
• A = 3.14 x 81
• A = 254.34 in²

Answer 2

Answer:

254.47 in²(rounded to nearest hundredth)

_________________________________________________________

$A = \pi r^2$

tiny r means radius

² means multiply the number by itself twice

$\pi r^2 = \pi * 9^2 = 81\pi(254.47~in^2)$
