Let's first find the area of each circle.Circle A:r = 12 / 2 = 6A = pi x 6^2A = 36pi in^2Circle b:r = 22 / 2 = 11A = pi x 11^2A = 121pi in^2Now, the ratio would be the area of circle A / circle B.36pi / 121pi = 113.10 in^2 / 380.13 in^2Hope this helps!! :)

Answer:Approximately 1/3Step-by-step explanation:Circle A has an area of approximately 113 inches, while circle B has an area of approximately 380 inches.

R.=6, C.≈38 and A.≈113. First you need to find the radius, the key term to find the radius is diameter=2⋅radius; therefore the radius r is 122=6 inches. To find the area of a circle, you need to use the formula A=π⋅r2; therefore the area A is π⋅62≈113 square inches. To find the circumference of a circle, you will use the formula C=2⋅π⋅r; therefore the circumference C is 2⋅π⋅6≈38 inches.

If the diameter is 8 inches, the radius is 4 inches. The Area of the circle is Pi* r^2 = 16 Pi square inches.
