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.

5 cakes cost 3.50 how much do 7 cakes cost
shtirl [24]

Answer:

$4.90

Step-by-step explanation:

If 5 cakes equal 3.50. We must divide 3.50 by 5 to see the price of just one cake. Now since 3.50/5 is 0.70. We must multiply 0.70 by 7. Since we have 7 cakes. Now we get our simple answer of $4.90.
