Answer:

105.57 cubic feet.

Step-by-step explanation:

A delivery truck arrived in the construction site and pouring a cone-shaped pile of gravel 6 feet high with a diameter at the base of 8.2 feet.

Therefore, the volume of the cone shaped pile is \frac{1}{3}\pi  r^{2}h, where r = \frac{8.2}{2}=4.1 feet and h = 6 feet.

Hence, V = \frac{3.14 \times(4.1)^{2}\times 6 }{3} =105.57 cubic feet.

So, 105.57 cubic feet of gravel was delivered. (Answer)

1. What percent of 58 is 18?
malfutka [58]

In order to find the answer you will have too divide 58 by 18 and then divide what you get from that by 100 to get your answer.

100%/x%=58/18

(100/x)*x=(58/18)*x    

100=3.22222222222*x      

(3.22222222222) to get x

100/3.22222222222=x

x=31.0344827586

Therefore your answer is "31%."

Hope this helps.

Superman needs to save Lois from the clutches of Lex Luthor. After flying for 6 seconds, he is 2430 meters from her. Then at 12
gayaneshka [121]

Answer:

2700.

Step-by-step explanation:

The total distance would be 2700.

Distance traveled between in 6th second and 12th second is 2430-2160=270 meter. That means Superman covered 270 meter in 6 seconds.

So, now if he is moving at the same speed, he should cover the same distance in first 6 seconds which is 270 meter.

Suppose the whole distance is X when time is 0, and after flying for 6 seconds he now is 2430 meter away. It means that he must have covered the distance of X-2430=270.

Finding for X, we gets the full initial distance, when time was 0.

The simple trick is, once we get the distance he has covered in 6 seconds, we can form the equation like subtracting the whole distance- remaining distance equals to covered distance.
