A company rents water tanks shaped like cylinders. Each tank has a radius of 5 feet and a height of 3 feet. The cost is 3 per cu
vova2212 [387]

Answer: the cost of renting one water tank is 706.5

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the given information,

Radius = 5 feet

Height = 3 feet

Therefore,

Volume = 3.14 × 5² × 3 = 235.5 cubic feet.

If the cost is 3 per cubic foot, then the cost of renting one water tank is

235.5 × 3 = 706.5

A regular hexagon has a perimeter of 60 in. What is the hexagon's area?
Jet001 [13]
Divide the perimeter by 5 since it is regular. 60/5 = 12. Split the hexagon into a triangle and a rectangle. Find the area of each and add them together. Area of the rectangle is 12*12 = 144. To find the area of the triangle, you need to find an angle measure= y, hypotenuse = c, and a leg = a or b. An easy way to find an angle measure is to cut down the altitude and find the angle next to the base and altitude which would be 90° due to the fact that the triangle is regular also. With the regular triangle split in half, you have two right angle which form both 90-45-45 triangles. Use this formula, A=ac \frac{siny}{2} --- A=12*12 \frac{sin45}{2} to find the area of the triangle which equals to 50.91. Add (((144+50.91 = 194.91))) I hope I got this right if not, i'm sorry lol.

3/8 to 7/8 find the percent of change and is it decrease or increase
mote1985 [20]

Answer:133.33%


Step-by-step explanation:

For given change in fractions from \frac{3}{8} to \frac{7}{8}

The initial fraction=\frac{3}{8}

New fraction= \frac{7}{8}

Change in fractions= New fraction-Initial fraction

=\frac{7}{8}-\frac{3}{8}\\\\=\frac{7-3}{8}\\\\=\frac{4}{8}\\=\frac{1}{2}

As change in fraction is positive thus it is an increase.

\text{Percent of increase=}\frac{\text{increase in fraction}}{\text{initial fraction}}\times100\\\\=\frac{\frac{1}{2}}{\frac{3}{8}}\times100\\\\=\frac{1}{2}\times\frac{8}{3}\times100\\\\=\frac{400}{3}=133.33\%

Answer:

24GB

Step-by-step explanation:

75.99-59.99=16   This is how much extra money was paid.

16/4=4                   Divide this by the cost per GB.

20+4=24GB          Add the 20GB included in the plan.
