Question

evelyn's made a cake in the shape of a circus tent to use as the centerpeice at the celebration. As shown in the illustration, the cake consisted of a cylinder and a cone. The height of the cone is half the height of the cylinder. The volume of the cylinder is 1470 incubed. The diameter of the cylinder is 12 in. What is the volume of the circus tent cake? Use 3014 for pi. Round to the nearest hundredth. Show you work

Answer 1

3.14

Answer 2

@sammixboo if ur not busy ;/ could u help me?

Answer 3

Use the volume and diameter of the cylinder to find the height, then use half of that height to find the volume of the cone and add it to 1470. Make sense?

Answer 4

okay so

1470= pi*36*h I dont know how to find the height tho

Answer 5

@Helloimjohn1234

Answer 6

You just solve for h like you would any other variable, you need to isolate it on one side

Answer 7

okay so what i did was pi*36=113.04 then i divided 1470 by 113.04= 13.004 but thats not right

Answer 8

If you use 3.14 instead of the pi value on a calculator, then 13.004 is correct. If you do use the pi button that stores all of the digits, then its 12.99765

Answer 9

okay but what do i do after 13.004?

Answer 10

sorry im not very good at math

Answer 11

So that is the height of the cylinder, divide it by 2 and use that value to find the volume of the cone using the formula, then add that volume to 1470

Answer 12

Note that the cone and the cylinder have the same diameter

Answer 13

1470=1/3(pi*36)h= 1/3(113.04 or 56.52)h

1/3*113.04= 37.68 1/3*56.52=18.84 which one?
