Nick is making a poster for Bike Safety Week. The diameter of circle A is 18 in.
If the area of circle B is the area of circle A, what is the area of circle B? (Use 3.14 for .)
First, we need to find the radius of circle A by dividing the diameter by 2:
Radius of circle A = 18 in / 2 = 9 in
Next, we need to find the area of circle A:
Area of circle A = π * (radius)^2
Area of circle A = 3.14 * (9 in)^2
Area of circle A = 3.14 * 81 in^2
Area of circle A = 254.34 in^2
Since the area of circle B is equal to the area of circle A, the area of circle B is also 254.34 in^2.
