VOLUME OF PYRAMIDS,

CONES, AND SPHERES

By: Daisy Luna, Noah Lusk, Othello Jimenez

VOLUME OF PYRAMIDSYou might only think of pyramids ancient

monuments, but there really used in modern day life, we are going to learn how to find there volume in today’s lesson.

FORMULA The formula for pyramids are easily

found. You take 1/3 of the area of the base times the height.

Here are some Example: 2 times 2 times 3

EXAMPLE 1 First you multiply 2 by 2 to get the area

of the base which is 4 Then you multiply 4 times 3 for area of

the base times the height which would be 12 as the volume.

EXAMPLE 2 Now work this one out on you're paper

ANSWER 5 multiplied by five would be 25 25 multiplied by 6 150 is the volume

VOLUME OF CONESKind of like pyramids, you can find cones

the same way as pyramids. Just 1/3 of base times height.

TYPES OF CONES There are mostly just the typical type of

cone. Flat bottom and a triangle top makes it seem like it will be very hard to find the volume, but as long as you break it down it’s a piece of cake.

PROCESS 1st off you will need to find the radius of

the bottom circle. Next you will need to measure the height of the cone.

Vcone = 1/3 × pi × r2 × h is the prime formula for the cone.

EXAMPLES The base of the radius of the circle is

5cm. The height of the cone is 10cm.
