Answer 1

*10m


PLEASE HELP i need answer ASAP

Answer 2

Hints:
\(
Volume\ of\ cylinder = \pi r^2 h \\
Volume\ of\ cone = \pi r^2h/3
\)
h refers to the corresponding height (of cylinder or cone).

Answer 3

soo cylinder = 314?
&&
the cone = 261.66~ ???

Answer 4

Not quite, can you please show your work?

Answer 5

Watch out that \( r^2 \) means r*r .

Answer 6

cylinder: 3.14(25)4
cone: 3.14(25)(10)/3
cylinder=314
cone=261.66~
thats what i got ?

Answer 7

The heights of the cylinder and cone have been interchanged. I don't know if that's a mistake or a wrong diagram.
Also, the formulae call for \( r^2 \) which means r*r.

Answer 8

if i put the link of the picture would you be able to see it?

Answer 9

I would, but not necessary as long as you have checked that the numbers are correct.
Your picture shows a cylinder of 10 high and a cone 4 high, but you have interchanged them in your calculations, hence my doubt.

Answer 10

ive checked and they are correct

Answer 11

@mathstudent55 can you please help me?

Answer 12

Did you know that the heights you used in your calculations do not correspond to those given in the diagram, which you said are correct?
