2. How to Find the Radius of a Circle When Given the Circumference
Step 1:
Find the circumference and
substitute.
Step 2:
Divide by π (usually 3.14 is acceptable for π).
Step 3:
Divide by 2.
Step 4:
Write the units.
Step 1:
Find the circumference
of the circle.
In this problem it's given As
Now that we know the
circumference, we must
substitute it into the
equation.
Circumference =2×π×radius
232.36=2×3.14×radius
232.36÷3.14=2×radius
74=2×radius
Step 2:
Divide by 3.14
74÷2=radius
Step 3:
Divide by 2
Step 4:
Write the units
= radius cm
