The area of a circle is 615.44 in 2. What is that number to other circle? Use 3.14 for the radius a 14 in B 18 in c 20 in d 24 inches e 28 in
The formula for the area of a circle is A = πr^2, where r is the radius of the circle.
By rearranging the formula, we can find the radius of the circle for the given area of 615.44 in^2.
615.44 = πr^2
615.44 = 3.14r^2
r^2 = 615.44 / 3.14
r^2 = 195.86
r ≈ √195.86
r ≈ 13.98 in
Given that the possible options for the radius are:
A) 14 in
B) 18 in
C) 20 in
D) 24 in
E) 28 in
The closest radius to 13.98 in is A) 14 in.
