What is the radius of this circle if the circumference is 183 cm?

C = 18

cm

o 3 cm

O 9 cm

O 18 cm

O 36 cm

The radius of the circle is 29.14cm

Step-by-step explanation:

To solve this problem we need to use the circumferenc formula of a circle:

c = circumference = 183 cm

r = radius

π = 3.14

c = 2π * r

we replace with the known values

183cm = 2 * 3.14 * r

183cm = 6.28 * r

183cm / 6.28 = r

29.14cm = r

The radius of the circle is 29.14cm
