Question

If a= 10 , in which of the following is closest to the area of the poster

A = 354 in
B = 275.5 in
C = 614 in
D = 535.5 in

Answer 1

The answer is D. 535.5

Answer 2

Answer:

A = 354 in

Step-by-step explanation:

Multiply the 3a and a, which are equal to 30 and 10, to get the area of the rectangle. This is 300. Then take the circle and use r^2pi for the area. Since you already calculated a quarter of the circle as part of the rectangle section. Multiply the circle area by 3/4 and that will get around 85. 300+85 = 385 which is closest to 354.
