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:
C ) y = -2x
Step-by-step explanation:
(2, -4)
y = -2x
subsitute x for the value of x
y = -2(2)
-2 × 2 = -4
y = -4
so
the equation for the point (2, -4) is
y = -2x
