Answer 2

@Mehek14

Answer 3

first we find the perimeter of the 2 semicircles

Answer 4

92? @Mehek14

Answer 5

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

Answer 6

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

Answer 7

@misssunshinexxoxo

Answer 8

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

Answer 9

ok

Answer 10

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