Answer 2

Answer:

To find the volume of a right circular cylin-

der, use the formula V = π r2h. V =

(3.14)(6)2(20) = (3.14)(36)(20) = 2,260.8 ≈

2,261 cubic feet.

The volume of concrete is 27 cubic feet. The

volume is length times width times the depth

(or height), or (L)(W)(D), so (L)(W)(D)

equals 27. We’re told that the length L is 6

times the width W, so L equals 6W. We’re also

told that the depth is 6 inches, or 0.5 feet. Sub-

stituting what we know about the length and

depth into the original equation and solving

for W, we get (L)(W)(D) = (6W)(W)(0.5) =

27; 3W 2 equals 27; W 2 equals 9, so W equals

To get the length, we remember that L equals

6W, so L equals (6)(3), or 18 feet.

. The amount of water held in each container

must be found. The rectangular box starts

with 16 square inches × 9 inches = 144 cubic

inches of water. The cylindrical container can

hold 44π cubic inches of water, which is

approximately 138 cubic inches. Therefore, the

container will overflow.

995. b. The volume of the box is 144 + 32 = 176

cubic inches. That divided by the base of the

box gets the height, 11 inches
