A circle has a radius of 10. An arc in this circle
has a central angle of 72°
What is the length of the arc?
Either enter an exact answer in terms of tror
use 3.14 for and enter your answer as a
decimal.

The answer is 20 pi over 5

Step-by-step explanation:

You start by finding the circumference which you would get 20 pi by doing 2 times pi times your radius which is 10 then you find the fraction of the circle using the central angle which is 1/5 then you multiply 1/5 by 20 pi which you would put over 1 which then gives you 20 pi over 5

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
