Question

What is the volume of a cone that has a radius of 6 inches and a height of 8 inches?

Answer 1

Use the formula

V = (pi*r^2*h)/3

Answer 2

In this case

r = 6
h = 8

Answer 3

Okay my answer is 301.44. Is that right?

Answer 4

what is the volume of a sphere?

Answer 5

Volume of Sphere

V = (4/3)*pi*r^3

Answer 6

I'm getting 301.44 as well

Answer 7

jim_thompson5910's formula of the Volume of a cone comes from the combination of the formula a pyramid \(V_\text{pyramid}=\frac13bh\)
( where b is the base and h is the height )
with the formula of a circle \(A_\text{circle}=b=\pi r^2\)

Answer 8

what is 678.24 / 4/3??

Answer 9

you're multiplying that with 4/3

Answer 10

oh! so what would it be? cuz idk how to do that on my calculator

Answer 11

(4/3)*678.24

Answer 12

type it in exactly as you see it

Answer 13

I do, but its not the right answer

Answer 14

what answer did you get

Answer 15

something in the 900's?

Answer 16

904.32 ?

Answer 17

ya

Answer 18

this is a sphere with a radius of 6 right? or something else?

Answer 19

yes a radius of 6, and I have to find the volume

Answer 20

how do they want you to round? and what do they want you use for pi?

Answer 21

to the nearest whole number, & 3.14

Answer 22

ok so 904.32 would round to 904

Answer 23

Yeah its still saying im wrong...

Answer 24

hmm

Answer 25

you'll have to bring this up with your teacher, 904 is the correct answer (according to what they want)

Answer 26

What is the surface area of a square prism?

Answer 27

SA = 2*(LW + LH + WH)

where

L = length
W = width
H = height

Answer 28

Okay to double check, whats the surface area for a cylinder?

Answer 29

SA = 2*pi*r^2 + 2*pi*r*h

Answer 30

Actually the surface area of a trapezodial prism?

Answer 31

For any prism, you basically find the areas of the bases, then you add on the lateral surface area (which is basically the sum of the lateral faces)

Answer 32

Yeah that makes no sense to me

Answer 33

try looking up a visual example then
