Question

The radius of the cone is 1.5 inches, and its height is 3 inches. If the diameter of the bubble gum ball is 0.5 inches, what is the closest approximation of the volume of the cone that can be filled with flavored ice?

Answer 1

21.21 in3
0.07 in3
7.00 in3
7.07 in3

Answer 2

@welshfella Help me please

Answer 3

Volume of a cone: V = 1 over 3 (πr2)(h)

Answer 4

Volume of a sphere: V = 4 over 3 πr3

Answer 5

I just am lost when it comes to plugging it in

Answer 6

@gottennis121 can you help
?

Answer 7

You must be i my class cause I'm doing the exact same lesson. lol. Use the formula: Volume = 1/3 x area of the base x height. So first, do you know how to find the area of the base?

Answer 8

I'm not entirely sure, can you remind me please?

Answer 9

I know that we have the radius though

Answer 10

To find the base area, use the formula for a circle which is pi x radius squared

Answer 11

you need to find the volume of the space underneath the bubble gum

Answer 12

Oh so i find the volume of the sphere (gum) first

Answer 13

Actually,

Use the formula

Pi x r^2

Answer 14

I don't know how to get the radius of the spherem since the diameter is 0.5 how could I possibly get half of that

Answer 15

find the volume of the cone first
then volume of the gum
then the volume of space under the gum
add the last 2 volumes
and subtract them from volume of the cone

Answer 16

Exactly, I believe something is wrong, since the radi is always the HALF of the diameter.

Answer 17

radi + radi, or radius^2 = Diameter.

Answer 18

I meant radi x radi .

Answer 19

I got 66.55 for the volumeof the cone

Answer 20

Is that right?

Answer 21

no
volume = 1/3 * pi * 1.5^2 * 3

Answer 22

7.065

Answer 23

Now, are you enabled to round the answer, or what?

(When you get it, XD )
