Answer:
20
Step-by-step explanation:
To find the diameter of a circle (that you know the circumference of), you use a formula.
The formula is: C=πd
variables:
C = circumference
d = diameter
You do not know the diameter, so this is the variable that you are solving for.
You DO know the circumference, so you can replace this variable with its number value as shown:
63=πd
The simplified version of this equation is:
d=63/π
the decimal form is:
20.05352282
36.864 cubic units is what the answer is
