Water is pulled up from a well in a bucket on a rope. The rope winds on a cylindrical drum
15 cm in diameter. It takes 28 turns of the
drum to pull the bucket
up
from the bottom
of the well. How deep is the well? (Use the
value
for ni.)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

i'm sorry i don't know

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
