Based on the amount of cheese used for the pizzas, the following are true:
- a. Mai uses 2.5 ounces of cheese per pizza.
- b. Mai will need 37.5 ounces for 15 pizzas.
<h3>Cheese used per Pizza. </h3>
This can be found as:
= Ounces of cheese used / Number of pizzas
= 10 / 4
= 2.5 ounces per pizza.
<h3 /><h3>Cheese needed for 15 pizzas. </h3>
= Number of pizzas x Cheese per pizza
= 15 x 2.5
= 37.5 ounces of cheese.
In conclusion, Mai needs 37.5 ounces of cheese to make 15 pizzas.

The total area of the figure will be 245 sq. in.
<h3>Total area of a cylinder</h3>
The figure is a cylinder and the total area of a cylinder is given by the formula below:
Total Area of a cylinder = 2πrh+2πr^2
Where r is the radius, h is the height of the cylinder, and π is constant with a value of 22/7.
In this case, looking at the image, the radius is 3" while the height is 10". Substituting these values into the formula above, we have:
Total Area = 22/7((2x3x10) + (2x3^2)) = 22/7(60+18)
= 245 sq. in.
Thus, the total area of the solid figure is 245 sq. in.
