Question

A dog that has been tethered with a 20-foot lead makes the path shown here. If the length of the path is 45 feet, the measure of the angle0 is _____ radians.

Answer 1

circumference = 2pi r
= 2 pi (20)
= 40 pi
= 125.6637

Set ratio:
45/40 pi = theta / 2pi
theta = (45/40pi) * 2pi
theta = 45/20
theta = 2.25 or 9/4 in fraction.

Answer 2

lol what do i put?

Answer 3

let's so with fraction if they let you enter the dash.

Answer 4
