Question

SOMEONE PLEASE HELP MATH

The circumference of a circle is 3π in.

What is the area of the circle?

1.5π​ in²
​ 2.25π​ in²
​ 6πin²
​ 9π​ in²

Answer 1

Circumference = 2πr = 3π
r = 3π/2π
r = 3/2

Area = πr² = 9/4 π = 2.25π

In short, Your Answer would be Option B

Hope this helps!

Answer 2

circumference = 2πr
3π=2πr
r=3π÷2π
r=3/2
area of a circle= πr²
=π×(3/2)²
=2.25π
