Question

math

Answer 1

So these are formulas you should memorize

Volume of cone = \(\dfrac{1}{3} \pi r^2h\)

or another way to write that would be

volume of cone = 1/3 * area of base * height

and they gave you the area of the base and the height

so can you find the volume?
(don't forget about the 1/3 since it's a cone)

Answer 2

ohhhh

Answer 3

pi*r^2 is the area of a circle

and what is the base of a cone?
it's a circle

(just for clarification if you're wondering how 1/3 * area of base * height is the same as that formula)

Answer 4

235.6?

Answer 5

but thats not in pi form

Answer 6

Try again and also remember we want to keep the answer in terms of \(\pi\) so that means you don't multiply the \(\pi\)

you just leave it sitting there

volume of cone = 1/3 * area of base * height

area of base = 4*pi
height = 6

volume = ??

Answer 7

so would th equation be 1/3*4*6?

Answer 8

exactly! and there's a pi there but you don't multiply by it since we want it in terms of pi

Answer 9

so then 15?

Answer 10

nope nope

what is 1/3 * 6 * 4 = ?

1/3 * 6 is the same as 6/3 = ??

and then multiply by 4

Answer 11

no it's 9 and 5

Answer 12

1/3*5*9

Answer 13

maybe you're looking at a different question?
#4

Answer 14

ohhhh

Answer 15

lol
i am

Answer 16

then it's 8

Answer 17

yup

and I'm not sure if you can write down \(\pi\) in that blank as well or if it's just assumed

but good job

Answer 18

thx

Answer 19

you're welcome
