932.58 in ^ 2 is needed
Step-by-step explanation:
What we need to do is calculate the area of all the circles and add it up, so we know how many square inches of paint are going to be needed.
We know that the area of a circle has the following formula:
A = pi * r ^ 2
there are 4 circles:
radio of 2 inches:
A = 3.14 * 2 ^ 2 = 12.56 in ^ 2
radio of 4 inches:
A = 3.14 * 4 ^ 2 = 50.24 in ^ 2
radio of 9 inches:
A = 3.14 * 9 ^ 2 = 254.34 in ^ 2
radio of 14 inches:
A = 3.14 * 14 ^ 2 = 615.44 in ^ 2
12.56 + 50.24 + 254.34 + 615.44 = 932.58
a total of 932.58 in ^ 2 is needed
