Answer:
254.34 in²
Step-by-step explanation:
Area of a circle
- A = πr²
- r = radius of the circle
Solving
- A = 3.14 x (9)²
- A = 3.14 x 81
- A = 254.34 in²
Answer:
254.47 in²(rounded to nearest hundredth)
_________________________________________________________
[tex]A = \pi r^2[/tex]
tiny r means radius
² means multiply the number by itself twice
[tex]\pi r^2 = \pi * 9^2 = 81\pi(254.47~in^2)[/tex]
