Best answer will get  brainliest!   a circular picture is 8 inches in diameter. part a what is the area of the picture in square inches?   a. 4 π square inches b. 8 π square inches c. 16 π square inches d. 32 π square inches part b a frame that is 2 inches wide surrounds the picture. what is the total area of the picture and the frame in square inches?   a. 4 π square inches b. 12 π square inches c. 36 π square inches d. 40 π square inches

We have to apply the formula to calculate the area of a circle. Area = π *R²

But since they have given us the diameter we have to divide it by two to obtain the radius.

R = diameter/2 = 8inches/2 = 4inches

Now we apply this value in the area formula :

Area = π *R² = (4 inches)²*π = 16inches²π = 16 π square inches

Answer A] : C.) 16 π square inches

If a 2-inch frame surrounds the figure, then we now have a circle with the radius increased by 2 inches.

R = 4 inches + 2 inches = 6 inches

Now we apply this new value in the area formula :

Area = π *R² = (6 inches)²*π = 36inches²π = 36 π square inches

Answer B] = C.) 36 π square inches

Hope this helps!

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
