If the circumference of a circle is 287, what is the
radius of that circle?

287/2π

Step-by-step explanation:

We know that the equation for the circumference is πd, so with πd=287, we can divide both sides by π to get d, the diameter, equal to 287/π. Then, we can divide both sides by 2 to get d/2, or the radius, equivalent to 287/2π

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )
