The circumference of a circle is 36π feet. what is the length of the radius of this circle?
9 ft
18 ft
36 ft
72 ft

18 ft

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

36 pi = 2 * pi *r

Divide by pi on each side

36 = 2 * r

Divide each side by 2

36/2 = 2r/2

18 =r

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
