@Mehek14

Mehek (mehek14):

first we find the perimeter of the 2 semicircles

OpenStudy (muscrat123):

92? @Mehek14

Mehek (mehek14):

the formula for the perimeter of a semicircle is \(\dfrac{1}{2}πd\)

Mehek (mehek14):

so \(\dfrac{1}{2}*3.14*46= 72.22\)

OpenStudy (muscrat123):

@misssunshinexxoxo

Mehek (mehek14):

you have 2 semicircles so \(72.22*2= 144.44\)

OpenStudy (muscrat123):

ok

Mehek (mehek14):

no add the length of the 2 sides 150+150 = 300 \(300+144.44=444.44\)

Mehek (mehek14):

now*

OpenStudy (muscrat123):
