The surface area of a right cylinder is the sum of the areas of the lateral face and the circular bases. The lateral face is really just a rectangle with the same height as the cylinder and a length equal to the circumference of the circular base.

If the radius of the base is $r$ and the height is $h$ , then the surface area of the cylinder is

$A=2\pi r^2+2\pi rh$

You're given that the area is $96\pi$ and the radius is $4$ , so you have

$96\pi=2\pi\times4^2+2\pi\times4h\implies 12=4+h\implies h=8$

A one-topping pizza costs $15.00. Each additional topping costs $1.25. Let x be the number of additional toppings. You have $20

pantera1 [17]

So,

Our total will be equal to 20. If we want 1 additional topping, we will have an additional $1.25. If we want 2 additional toppings, we will have an additional $2.50. So we can just multiply the number of additional toppings by 1.25 to get the additional amount.

1.25x

However, you will have already spent $15.

1.25x + 15 = 20

This is option B.

P.S. You will be able to put exactly 4 additional toppings.

Express each fraction as a percent 7/20

Sergio [31]

To find out what percent 7 out of 20 is, we need to ask: 7 out of 20 is how many out of 100? 5 groups of 20 make 100, so 7 out of 20 is 35 out of 100 (5 x 7 out of 5 x 20). Therefore 7/20 equals 35%, or 0.35 if we represent it as a decimal. I hope this helps
