What is the volume of a cone that has a diameter of 16 inches and a height of 4 inches
Answer: 268.08 inches cubed How to get it: First you must find the area of the circular base. In order to do that you need the RADIUS so divide the diameter by 2. SO, you take 8 times 8 times pi to get the area of the base. Take that times the height. Then, since it is a cone, you have to divide that answer by 3.

Dean made a batch of 24 cookies. He gave 1/3 of them to Caleb. How many cookies does Dean have left?
Answer: Dean has 16 cookies left. How to get it: Find 1/3 of 24 by dividing 24 by 3 and then taking that times 1. That gives you 8. 8 cookies are how many Dean gave to Caleb so you have to take 8 away from 24 to find how many cookies Dean has left.

What is the area of a circle with a diameter of 12? What is the circumference of the same circle?
Answer: Area = 113.09 square inches / Circumference = 37.69 inches How to get it: Area you take the radius times the radius times pi. For the Circumference you take the diameter times pi.

What is the volume of a triangular prism if it has the following measurements: Triangular base - base length of 6cm and height of 8cm Height of the Prism - 9cm
Answer: 216 centimeters cubed How to get it: Find area of the base by taking 6 cm times 8 cm. Then, since it is a prism, we just take that area of the base times the height of 9 cm.

Samantha has a glass of water. The glass is a cylinder with a height of 8 inches. The diameter of the glass 3 inches. If the glass is 1/4 full of lemonade. How many cubic inches of lemonade are in the glass?
Answer: There are about 14.13 cubic inches of lemonade in Samantha's glass. How to get it: Find the area of the base by taking 1.5 times 1.5 times pi. Then multiply that by the height of 8 inches. Finally, divide by 4 because you need 1/4th of the total volume of the glass since the glass is only 1/4th full.

What is 3 and 1/2 times 2 and 1/3 ?
Answer: 49/6 or 8 and 1/6 How to get it: First make the mixed numbers into improper fraction. 3 and 1/2 becomes 7/2. 2 and 1/3 becomes 7/3. Multiply 7/2 times 7/3 by multiplying the numerators and then multiplying the denominators.

Alex bought an ice cream cone, and believe it or not the cone was in the perfect shape of a cone. Half of the radius of the base measured 2 inches and the height of the cone was 5 inches. How many cubic inches of ice cream can the cone hold?
Answer: Alex's cone can hold about 83.77 cubic inches of Ice Cream. How to get it: Find the area of the circular base by taking 4 times 4 times pi (because HALF of the radius is 2 inches). Then multiply that by the height of 5 inches. Finally, since it is a cone you have to divide all that by 3.

Maddie has a large, hollowed out, dice (it's a cube). One side of it is 8 inches long. Maddie wants to drink soda pop out of the dice. How many cubic inches of soda pop could her dice hold?
Answer: The dice could hold 512 cubic inches of soda pop How to get it: It is a cube so all of the sides are the same length. To find the volume of a cube you find the area of the base and times that by the height. So you just multiply 8 times 8 to get the area of the base. Then multiply that by 8 since 8 is the height.

Natalie has a rock that is in the shape of an octahedron (remember that is two pyramids stuck together). The pyramid that makes up half of the octahedron has a height of 4 inches and a square base with a side length of 4 inches. What is the volume of Natalie's octahedron rock?
Answer: Natalie's rock has a volume of about 42.66 cubic inches. How to get it: First, find the volume of the pyramid that makes up half of the octahedron. Do that by taking 4 times 4 times 4 and then divide by 3. Take that answer times 2 since the octahedron is made up of 2 of the pyramids you just found the volume of.

If there is a truncated rectangular pyramid, how many faces, vertices, and edges does it have?
Answer: 6 faces, 8 vertices, 12 edges How to get it: You have to know what truncated means, and then just visualize the solid in your mind. Notice that the faces + vertices - 2 works for this as well!!
