An arc of a circle is 3πm long, and it subtends an angle of 72° at the center of the circle. find the radius of the circle. the radius of circle that is how it should be put as answer.

Using the arc length equation  x 2πr, you can solve for the radius. So, the radius of the circle is 7.5m. 

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

These are the multiples of 15 but what you are probably asking or what are the factors of 15
