Which of the following statements about the volumes of the cans is true?

A. The volume of can A is half the volume of can B.

B. The volume of can B is four times the volume of can A.

C. The volumes of the two cans are equal.

D. The volume of can B is half the volume of can A.

I think C or D.

Answer 1

wait

Answer 2

b is bigger

Answer 3

Use the formula
\[\Large V = 3.14*r^2*h\]
r = radius, h = height

to find the volume of each cylinder. This will be the approximate volume

Then compare the two volumes.

Answer 4

@ShelbyWyatt So it would either be B or D then?

Answer 5

cant b "d" d is a is bigger than b

Answer 6

So... it would be B? @ShelbyWyatt

Answer 7

a or b

Answer 8

which do you think

Answer 9

lets find the approx area of both first

Answer 10

What would be the formula to find the area? Sorry, still new to this @ShelbyWyatt

Answer 11

v=3.14*r^2*h

Answer 12

How do I find the radius of them?

Answer 13

1.3 and 2.6 is the radius

Answer 14

oh okay, let me work it out.

Answer 15

you want volume, not surface area. But you have the right formula

Answer 16

Wait, do I do it for both cylinders?

Answer 17

yeah

Answer 18

so first will be v=3.14*(1.3*1.3)*10

Answer 19

second will be v=3.14*(2.6*2.6)*5

Answer 20

For the first one I got 53.066
The second one I got 106.132
@ShelbyWyatt

Answer 21

so that makes a the answer

Answer 22
