A. volume of the stage in the banquet hall = 22 x 15 x 4 = 1,320 cubic foot.
weight of the stage in the banquet hall:
1 cubic foot weighs 62.4 pounds
1,320 cubic feet will weigh 1,320 x 62.4 = 82,368 pounds.
b. volume of each cylindrical pillar = pi * r^2 * h = pi * (1/2)^2 * 9 = pi * 1/4 * 9 = 7.069 cubic feet
weight of each cylindrical pillar:
1 cubic foot weighs 62.4 pounds
7.069 cubic feet will weigh 7.069 x 62.4 = 441 cubic feet.
The value of 9 in 49.21 is 9.00
but the value of 9 is 982.3 is 900
Number of combinations =( 4 x 3 x 2) / (1 x 2 x 3) = 4
Answer: 4 Combinations
Let's say

is the measure of the first angle and

is measure of the supplement of

. We know that supplementary angles add up to 180°, so

. We also know that

. Therefore,

. It follows that

, therefore, the first angle is 174° and the second angle is 6°.
