Find the exact radius of a circle with circumference 28pi meters.

Answer: The radius is 14 units.

Step-by-step explanation:

Start by finding the diameter, the formula for circumference is πd, So set up an equality:

28π=c

28π=πd

Divide both sides by π:

28π/π = 28πd/π

Cross out π:

28 = d

diameters twices largest radius, divide your diameter by 2 to get radius.

D/2 = r = 28/2 = 14

Therefore, your radius is 14 units.
