Question

ind df/dy of f(x,y) =x^y. anyone helps me, please

Answer 1

all volume formulas are legit, right?
if so, you can use the V = B(h) formula, so you would multiply 6 by [18(18)]

Answer 2

correct!
let's review the math:
V = 18^2(6)
18 squared is 18 times 18
V = 324(6)
so
V = 1944

Answer 3

that would be 1944 in.

Answer 4

I mean c

Answer 5

you know what? I am so sorry! I had you solving for a cube!!! i'll be right back with the correct equation...

Answer 6

Ok, take a look at this: http://mathsteacher.com.au/year10/ch14_measurement/25_pyramid/21pyramid.htm

Answer 7

so, you will need to do equation:
V = 1/3 (area of base*height)

Answer 8

that would be V = 1/3 [(18*18) * 6]
V = 1/3 (324 * 6)
V = 1/3 (1944)
V = 640
You are correct! the answer is C
