Question

The circumference (C) of a circle i 18 centimeter. Which formula can you ue to find the radiu (r) if you know that C =

Answer 1

Answer:

Radius is equal to 2.86 cm

Step-by-step explanation:

C = Perimeter = 18 cm

Perimeter of a circle = 2*PI*r

C = 2*pi*r

18 = (2)*(3.14)*r

18 = 6.28*r

r = 18/6.28

r = 2.86 cm
