Answer:

The volume of the cylindrical tank is 176.625 cubic feet.

Step-by-step explanation:

Given : The tank is 9 feet high and has a diameter of 5 feet.

To find : Marjorie needs to calculate how much water a cylindrical tank will hold ?

Solution :

The volume of a cylinder is $V=\pi r^2 h$

The diameter is d=5 feet

The radius is $r=\frac{d}{2}$

$r=\frac{5}{2}=2.5$ feet.

The height is h=9 feet.

Substitute the value in the formula,

$V=3.14\times (2.5)^2\times 9$

$V=3.14\times 6.25\times 9$

$V=176.625$

The volume of the cylindrical tank is 176.625 cubic feet.

Answer:

∠ ADC = 145°

Step-by-step explanation:

The central angle is equal to the measure of the arc that subtends it, then

∠ ADE = 70°

∠ EDC = 75°

∠ ADC = ∠ ADE + ∠ EDC = 70° + 75° = 145°
