Question

7th-8th grade math! EASY (not for me) medals and fan!

Answer 1

How many more cubic inches of juice will cup B hold than cup A when both are completely full? Round your answer to the nearest tenth. (1 point)


8.8 cubic inches
10.1 cubic inches
14.7 cubic inches
22.3 cubic inches

Answer 2

Yes, I tried doing this but got an answer that was not any given

Answer 3

Your questions wants you to calculate the volume of each 3d shape. After that, analyze how much a shape is bigger than the other.

Answer 4

Yes that is what I tried doing

Answer 5

Can i see your work that you've done so far?

Answer 6

Yes

Answer 7

hold on let me type it

Answer 8

Cup A: 1/3 (3.14) (2 to the power of 2) (4)
I multiplied everything but 1/3
and then divided by 3
and got 16.74


CupB: (3.14)(2 to the power of 2) (6)
multiplied everything and got 75.36

Answer 9

And then if Im correct I subtract them and I got 58.62

Answer 10

Can you please help?

Answer 12

I got 8.33 in^3 for the cone and 37.47 in^3 for the cylinder.

Answer 13

Oh ok, I will try that! Thanks, brb

Answer 14

hmmm weird

Answer 15

this has to be wrong then, they could of made a mistake in this question

Answer 16

I had the same problem with another question where it asked the volume of a sphere with a radius of 9. And the answer I got witch I checked online, was not one of the choices

Answer 17

may I jump in? :)

Answer 18

For the volume of the cone we need to use \(\pi r^2 \dfrac{h}{3}\)
So, \(\pi * 1^2 * \dfrac{4}{3}\)
\(1^2 = 1\)
\(\pi*1*\dfrac{4}{3}\)
\(\pi * \dfrac{4}{3}\)
V \(\approx\) 4.19
For the volume of the cylinder we need to use \(\pi r^2 h\)
So, \(\pi * 1^2 * 6\)
\(1^2 = 1\)
\(\pi * 1* 6\)
\(\pi * 6\)
V = 18.84

Now, subtract the volume of the cone from the volume of the cylinder :)

Answer 19

Y'all forgot that radius is half of diameter :)

Answer 20

Whoops, cylinder should actually be \(\approx\) 18.85
