Answer 1

figure...?

Answer 2

first find the length of the arc...

length= (n degrees/360) * 2 * pie * r
length = (90/360) * 2 * 3.14 * 5
length= 0.25 * 31.4
length= 7.85....

now find the perimeter... which is R+R+arc length = 5+5+7.85 = 17.85 inches... @lovablenene

D.
153.86 in.

Answer 6

ahh... just use the formula... C = 2pi r... ok... now we have given the diameter... which is 14 here... we will need the radius... radius= diameter/2 = 14/2= 7... put this in the formula... C=2 * 3.14 * 7= 43.96inches... @lovablenene
