Answer:

6√2

Step-by-step explanation:

Solving the given expression step by step:

72 = 2 × 2 × 2 × 3 × 3

Now for finding the square root we will make pair of two numbers of same values.

We have one pair of 2's and one pair of 3's and left one 2

Thus, √72 = 2 × 3 × √2 = 6√2

We rationalize denominator and change it into a simpler form as soon as possible.

An oil tank in the shape of a cylinder has a diameter of 40 feet and a height of 32 feet. Which expression can be used to find t
Volgvan

The volume of a cylinder is pi*r^2*h

The radius is half the diameter, so 40/2=20, and the radius is 20 ft.

Plugging in: pi*20^2*32=pi*400*32=12800pi=40212.38597

So the volume is about 40212.4 ft^3 and the expression we used is pi*20^2*32

Hope this helped!
