Answer 1

So it looks like we have....a rectangle...and a half a circle...

The rectangles perimeter is easy...

just add up the 8 + 8 + 9 + 9 = 34

Now with that semi-circle...we need to find the circumference of the circle....because that is the length of the outside of the circle...but then divide it by 2 since we only have half

\[\large C = \pi d\]

We know the full diameter is 8 (look at the length of the rectangle above it...it is 8 inches long....

So we have the circumference = pi times 8 which is AROUND 25.13 ...so divide that by 2 to get 12.566

So add those 2...we have 34 + 12.566 = 46.566

Answer 2

do you know it @johnweldon1993

Answer 3

Well that is the answer I get @itsbribro
The closest answer to yours would be B...even though that SHOULD be incorrect
