The volume of a right cylindrical water tank is 5000 cubic meters. The radius of the base of the tank is 20 meters. Find the length in meters, of h, the hight of the tank. A. 15 m B. 10 m C. 10.5 m D. 12.5 m

10 m

Explanation:

The volume of a cylinder is given by

V = pi r^2h

We know the radius is 10 and the volume is 1000pi

1000pi = pi (10)^2 h

1000 pi = 100 pi h

Divide each side by 100 pi

1000 pi/100pi = 100 pi h/100pi

10 = h

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
