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 [tex]V=\pi r^2 h[/tex]
The diameter is d=5 feet
The radius is [tex]r=\frac{d}{2}[/tex]
[tex]r=\frac{5}{2}=2.5[/tex] feet.
The height is h=9 feet.
Substitute the value in the formula,
[tex]V=3.14\times (2.5)^2\times 9[/tex]
[tex]V=3.14\times 6.25\times 9[/tex]
[tex]V=176.625[/tex]
The volume of the cylindrical tank is 176.625 cubic feet.
Answer:
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
Hope this helped :)
