Find the length of the arc on a circle of radius r intercepted by a central angle 𝜃. (Round your answer to two decimal places.)

Question

​Radius, r=11 ​inches;

Central​ angle, θ=40

Answer 1

To find the length of arc, we need to use the formula θ/360 x π x r^2.

Now, we can plug in the numbers according to the formula: 40/360 x π x (11)² which would give us 42.24.

Hence, the length of the arc is 42.24 inches.
