How do you find the radius of a circle knowing the circumference

C=2 pie r (example circumference=28) 28=2 x 22\7 x r 28=6.29r then divide both sides by 6.29 28\6.29=4.45 r=4.45

Logical equivalent of the give question is its contrapositive

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
