A company rents water tanks shaped like cylinders. Each tank has a diameter of 8 feet and a height of 3 feet. The cost is $5 per
1 answer:
Answer:
$754.05
Step-by-step explanation:
We have to find the volume of one tank and multiply it by the cost of renting the tank per cubic foot.
The volume of a cylinder is:
where r = radius
h = height
Each tank has a diameter of 8 feet (radius = 4 feet) and a height of 3 feet.
The volume of the tank is therefore:
The cost of renting is $5 per cubic foot.
Therefore, the cost of renting a tank is:
150.81 * 5 = $754.05
It costs $754.05 to rent a tank.

Answer:
- <u><em>Rounding to nearest tenth of centimeter, the ball bounces 192.1 cm high on the 5th bounce.</em></u>
<u><em></em></u>
Explanation:
The <em>ball is dropped from a height of 900 centimeters</em>.
Since the heights form a <em>geometric sequence,</em> you can find a common ratio between consecutive terms. This is:
- Height bounce 2 / height bounce 1 = 560 / 800 = 0.7
- Height bound 3 / height bounce 2 = 392 / 560 = 0.7
Hence, the ratio of the geometric sequence is 0.7, and taking bounce 1 as the start of the sequence, the general term of the sequence is:
With that formula you can find any term:
Rounding to <em>nearest tenth of centimeter</em>, the ball bounces 192.1 cm high on the 5th bounce.
