question 2-janet made a model of the great pyramid of giza in egypt. the length of the base of her pyramid is 9 inches and the width is 5 inches. the height of her pyramid is 12 inches. find the volume of her pyramid.

question 3- jaquan is a basketball star. the basketball has a radius of 5 inches. what is the volume of the basketball?

Question 1:

Question 2:

Question 3:

Step-by-step explanation:

1- Let's assume that the Rockefeller Center Christmas Tree is a cone.

This formula is used to find the volume of a cone:

Where "r" is the radius and  "h" is the height.

In this case we know that:

Then, substituting values into the formula and solving for "r", we get:

2- We can use this formula for calculate the volume of the rectangular pyramid:

Where "l" is the length of the base, "w" is the width of the base and "h" is the height of the pyramid.

Knowing that:

We can substitute values into the formula to find the volume of her pyramid:

3- The formula for calculate the volume of a sphere is:

Where "r" is the radius.

Knowing that the the radius of the basketball is:

We get that its volume is:
