Answer:

The formula for calculating the circumference (C) of a circle, C = πD or C = 2πR, is simple if you know the circle's diameter (D) or radius (R). But what do you do if you only know the circle's area? Like many things in math, there are multiple solutions to this problem. The formula C = 2√πA is designed to find a circle's circumference using the area (A). Alternatively, you can solve the equation A = πR2 in reverse to find R, then plug R into the circumference equation. Both equations provide the same result.

Step-by-step explanation:

Answer:

The value of y is 36, and the value of z is 54.

Step-by-step explanation:

y has to be a number that can sit at 2y and then add itself to itself and become 3y.

40 is too high, and 35 is too low. Level it out, and you get 36.
