A clock tower has a circular clock face with a circumference of 48π feet. What is the radius of the clock face ?

KatRina [158]

Answer:

r = 24 ft

Step-by-step explanation:

Circumference is given by

C = 2 * pi *r

We know that C = 48 pi

48 pi = 2 * pi * r

Divide each side by pi

48 pi /pi= 2 * pi * r/pi

48 = 2 r

Divide each side by 2

48/2 = 2r/2

24 = r
