Marjorie needs to calculate how much water a cylindrical tank will hold. the tank is 9 feet high and has a diameter of 5 feet. her work is shown below. step 1: step 2: step 3: step 4: cubic feet what error did marjorie make when calculating the volume of the tank?

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

The diameter is d=5 feet

The radius is

feet.

The height is h=9 feet.

Substitute the value in the formula,

The volume of the cylindrical tank is 176.625 cubic feet.

Option B, "In step 2, she calculated 2.5 squared incorrectly."

Step-by-step explanation:

She got the formula correct, but when she multiplied 2.5 squared, she wrote 5, but the correct answer is 6.25. Thus, the correct answer is option B
