In a triangle, the sum of the interior angles is 180.

So, you have

$A+B+C=180$

Plug the values for angles A and C:

$75+B+20=180 \iff 95+B=180 \iff B=180-95=85$

A company rents water tanks shaped like cylinders. Each tank has a radius of 3 feet and a height of 2 feet. The cost is $ 4 per

Alexxandr [17]

Answer:

The total cost of the cylindrical tank is $226.28

Step-by-step explanation:

Dimensions of the tank are: radius = 3 ft , height = 2 ft

Cost per cubic foot = $4

Now, total volume of the cylindrical tank = $\pi \times r^{2}h$

Here, take π = 22/7

So, Volume = $\frac{22}{7} \times (3)^{2} \times (2) = \frac{22 \times 9 \times 2}{7} = \frac{396}{7} = 56.57 cubic ft$

So, the <u>volume of the tank = 56.57 cubic feet. </u>

Now, cost per cubic foot = $4

Hence, the total cost of the tank = Total Volume of the tank x cost per foot

= 56.57 x 4 = $226.28

So, the total cost of the cylindrical tank is $226.28
