I chose answer A

Answer 1

I believe it is also A but let me check again..

Answer 2

A is correct

Answer 3

A is correct, and you are hot

Answer 4

A is not correct:

Area of the rectangle:
\[A=wl\]\[A=7*13=91\]

Area of the half-circle:
\[A=\frac{1}{2}*\pi*r^{2}\]\[A=\frac{1}{2}\pi*3.5^{2}=19.23\]
Total area:
\[A=A1+A2=91+19.24=110.23\]




The answer is C.

A would be right if it was a FULL circle, but its not.

Answer 5

7*13 would be the area of the Rectangle. That comes to 91. Keep that in back of your head.

If you take a close look at the semi-circle, you'll see that the diameter is 7 inches. Imagine a whole circle with radius (7/2) inches, or 3.5 inches. Pi*(radius^2) = area, so 3.14*(3.5^2) = a total area of 38.48. But this is a half-circle. Not a whole circle. So divide the total area in half to get: 19.24 inches. Take this area of the semicircle and add it to the area of the rectangle. That'd be 91+19.24: You get 110.24 inches sqt.

Twvogels is right, y'all.
