Mathematics

B. 14M

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:

28ππ=πdπ

28=d

Diameter is twice as large as radius, so divide your diameter by 2 to get radius.

d2=r=282=14

Therefore, your radius is 14 units.
