Question

Find the Perimeter of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place.

Answer 1

We want the perimeter so we have to also calculate the circumference of the semi-circle

Answer 2

32?

Answer 3

the circumference of a normal circle is \( 2\pi r\) but since it's half a circle, it's just going to be \(\pi r\) and r is half of the diameter which is 4

Answer 4

???

Answer 5

No, the green lines is the perimeter

Answer 6

6.28?

Answer 7

Good, that's the circumference or perimeter of the half circle

now just add the 3 sides of the parallelogram

so 6.28 + 6 + 6 + 4 = ?

Answer 8

22.8
