Acircle has a radius of 5 ft, and an arc of length 7 ft is made by the intersection of the circle with a central angle. which equation gives the measure of the central angle,  q?

arc length, s=(radius, r)(angle in radians, q)

q=tan^-1(s/r)

SO that saying the answer is 1.4 radians and the equation is probs q=7/5=1.4

I think it's theta = 7/5

Step-by-step explanation:

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
