Question

if a circle has a diamter of 7 inches, what is the circumference rounded to the nearest whole number? use 3.14 for pi.

Answer 1

Circumference is πd where d is the diameter. You can derive this to isolate diameter by dividing both sides by π.

D=Cπ. Now just plug the numbers for your variables.

D=75.363.14

D=24

The diameter is 24 yards.
