Question

Hey,
Could you help me find the volume for the figure below?

Answer 1

so it has the same thickness the entire way along, and the width is also constant, so all you need to find is the length... yeah?

Answer 2

yes

Answer 3

darn... i actually have no idea on how to find the length of a sinusoidal wave... @rational , are you able to step in please?

Answer 4

Sure. Thanks :)

Answer 5

@rational Could you solve it?

Answer 6

if it is a pure sine curve you can obtain the length by setting up an integral

but from the specification it doesn't look like a sine curve

Answer 8

Its fillet. Its sine curve.

Answer 9

If its sine curve, how it can be solved?

Answer 10

start by writing the function

Answer 11

\[f(x) = A\sin(Bx+C)\]

Answer 12

find out A, B, C values and plugin above

Answer 13

what is A, B and C?

Answer 14

look at the first diagram, whats the period of sine wave ?

Answer 15

thats the total length, not period.

Answer 16

1 for each!

Answer 17

@iGreen

Answer 18

I think it is a trick question put in water and find volume displaced

Answer 19

Anyone could solve it?
