Question

The circumference of a circle is 81.64 kilometers. What is the circle's diameter?C = 81.64 kmUse 3.14 for л.kilometers

Answer 1

Circumference formula:

`C=\pi *d`

Solve d (diameter):

`d=(C)/(\pi)`

Use the formula above and the given data to find the diameter of the circle:

`d=(81.64km)/(3.14)=26km`

Then, the diameter of the given circle is 26km
