Q:

A circular ice skating rink has a diameter of 65 feet. What is the circumference of the rink, rounded to the nearest tenth.F:204.2 ftG:261.3 ftH:408.4 ftJ:522.6 ft

Accepted Solution

A:
The meaning of circumference is to find the distance around a circle or in other words the perimeter of the circle. The circumference of a circle can be calculate by using the formula C=2πr or C=πd.

In this exercise is given that a circular ice skating rink has a diameter of 65 feet, and it is asked to find its circumference. In this problem the diameter of the circle is given, so in this case the formula C=πd would be used, where d represents the diameter.

C=πd
C=π(65 ft)
C=204.2 feet

The circumference of the circular ice skating rink is 204.2 feet.
