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 ft

G:261.3 ft

H:408.4 ft

J:522.6 ft

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.

Cicumference = 2*pi*r remember pi = 3.14

radius * 2 is the same as diameter (you can use either one)

so solve:

C = 3.14 * 65

C = 204.1
