Ok so first, you add $8.50, $10.25, and $2.25 to get the total bill of $21. Since 3 people are splitting the bill equally, divide $21 by 3 to get $7. Hope this is helpful!

The height of a cylinder is equal to the diameter of the base. What expression represents the volume of the cylinder, in cubic u

OverLord2011 [107]

The volume of the cylinder will be 2π $R^{3}$

As shown in figure, R is the base radius of the cylinder.

H is the height of the cylinder.

Given: H = diameter of the base of cylinder.

Now, diameter of the base = 2R

So, H = 2R

Volume of cylinder = π× $R^{2}$ ×H

= π× $R^{2}$ ×(2R)

= 2 π $R^{3}$ cubic units.
