Answer:
Start by finding the diameter; the formula for circumference is
πd , so set up an equality:
28π = c28π = πd
Divide both sides by
π :28ππ=πdπ28ππ = πdπ28=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.
Step-by-step explanation:
Circumference of circle = 28m
circumference= 2πr
28=2×22/7×r
r=4.4m
Thus, the radius of circle is 4.4m
