Find the radius of a
circe given the area
25pi square inch.

Radius = 5 inches

Step-by-step explanation:

1) We have to use the equation for the area of a circle to find the radius of the circle.

Area of a circle = πr^2

2) Plug in the information we already know, i.e., the area.

25π = πr^2

3) Cancel out the π on each side.

25 = r^2

4) Take the square root of 25

r =

r = 5

5) The radius is 5 inches.

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,

15% chance.
