determine the area of the shaded region.use 3 for pi.
picture shows three circles two small circles inside of one big circle both of the circle are 7 in.
A.196 square inches
B.294 square inches
C.462 square inches
D.588 square inches
so, how big is the large circle?
What is the shaded area?
The two small circles each have area 49 pi = 147 in^2
other than that, there's not much I can tell you.
Maybe B, since that is the area of both small circles.
B is the answer
thanks Ms. Sua
i feel like its B but idk
your wellcome
Bruhh what is it
To determine the area of the shaded region, we need to find the area of the big circle and subtract the sum of the areas of the two smaller circles.
1. Find the area of the big circle:
The formula to calculate the area of a circle is A = πr^2, where A is the area and r is the radius. In this case, the radius of the big circle is 7 inches. Therefore, the area of the big circle is:
A_big = π * (7)^2
Since we are asked to use 3 for pi, the formula becomes:
A_big = 3 * 49
A_big = 147 square inches
2. Find the area of each smaller circle:
Both smaller circles have the same radius as the big circle, which is 7 inches. So, the area of each smaller circle can be calculated using the same formula:
A_small = π * (7)^2
Using 3 for pi:
A_small = 3 * 49
A_small = 147 square inches
3. Subtract the sum of the areas of the smaller circles from the area of the big circle to get the shaded region:
Shaded area = A_big - (A_small + A_small)
Shaded area = 147 - (147 + 147)
Shaded area = 147 - 294
Shaded area = -147 square inches
Since the calculated shaded area is negative, this indicates that there might be an error in the problem statement or the question itself. Therefore, none of the given options (A, B, C, D) would be the correct answer for the area of the shaded region.
