Question

Screenshot below.

Answer 1

I got 6624 for the area of the rectangle and 3737.385 for the area of the semi circle

Answer 2

you don't want to find the area, you want to know the distance around the figure, or the perimeter

Answer 3

so you want to find the circumference of the semicircles

Answer 4

\[C~=~2\pi r\]

Answer 5

wait what's the plus 2(96)

Answer 6

the circumference of the whole circle would be 216.66. the perimeter is 216.66 + 96 + 96 because the length of the rectangle is 96

Answer 7

so is it 216.66 x2 because theres two circles?

Answer 8

no. C = 2 pi r is the circumference of a whole circle. since the two semicircles have the same measurements, we can basically say there's just one circle. so C = 216.66 is the circumference for both semicircles

Answer 9

and then 96 + 96 ?

Answer 10

so 216.66/2 is 108.33. so 108.33 for each semicircle.

look below to see

Answer 11

see where the 96s come from?

Answer 12

yeah thats the rectangle

Answer 13

exactly. so 96 + 96 + 108.33 + 108.33 is your answer

Answer 14

so 408.66 ?

Answer 15

yes

Answer 16

thank you!
