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

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 <span>this problem the diameter of the circle is given, so in this case the formula C=</span><span>πd would be used, where d represents the diameter.

C=</span>πd
C=π(65 ft)
C=204.2 feet

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

Answer:

The hikers are 5.9 miles apart.

Step-by-step explanation:

Let O represents the base camp,

Suppose after walking 3.5 miles west, first hiker's position is A, then after going 1.5 miles north from A his final position is B,

Similarly, after walking 2 miles east, second hiker's position is C then going towards 0.5 miles south his final position is D.

By making the diagram of this situation,

Let D' is the point in the line AB,

Such that, AD' = CD
