Solve c = 2πr (solve for "r")
c = 15

For this case we have the following equation:

From here, we clear the value of r:

Substituting the values in the obtained equation we have:

Doing the calculations we have:

The value of r is given by:

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.
