Question

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

A. Theta=5/7
B. Theta=7/5
C. Theta=7+5
D. Theta=7•5

Answer 1

Answer: Theta = 7/5

Explanation:

Use the arc length formula
`s=r(theta)`

Rearrange the formula since you are wanting to solve for theta

so
`theta = (s)/(r)`

Plug in

theta = 7/5
