Acircular 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

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

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b
