Use the arc length formula and the given information to find θ. s = 7 m, r = 12 m; θ = ?
Imagine that this arc length is on a circle. The ratio of the arc length to the arc's angle is the same as the ratio of the entire circle's circumference to a complete rotation of 360 degrees around the circle. So you can set these ratios equal to each other and solve since they're both on the same circle.
HI Lauren01 do you know the formula for the arc length ?
so Q=s/r just sub the given here
