Answer 1

Do you know the formula for the volume of a pyramid and cylinder?

Answer 2

no

Answer 3

For a Pyramid \[V = \frac{ lwh }{ 3 }\] \[V = \frac{ 5 \times 5 \times 6 }{ 3 }\] And for the cylinder we have \[V = \pi r^2h\]\[V = 3.14 \times 1^2 \times 50\]

The radius is one, so we just square it.

Alright, so now that we have all that out of the way, we simply solve for both and compare.

Answer 4

So which one would it be?

Answer 5

Figure A?

Answer 6

Show me your work. Solve both then post the results.

Answer 7

Ahh can you just help me out here :p

Answer 8

To get figure A; solve:
\[V = \frac{ 5 \times 5 \times 6 }{ 3 }\] And to get figure B; solve: \[V = 3.14 \times 1^2 \times 50\]

Answer 9

Basically, all I did was use the formulas and plug-in the known values.

Answer 10

A: 50
B: 157

Answer 11

B is larger?

Answer 12

Correct!

Answer 13

Thanks!
