Question

what is the derivative of:
A = (3pi)(9+h)(sqrt(18-2h))

Answer 1

\[A = (3\Pi)(9+h)(\sqrt{18-2h})\]

Answer 2

@sami-21

Answer 3

use product rule
where 3 pi is constant
\[\Large \frac{d}{dh}(f*g)=\frac{d}{dh}(f)*g+\frac{d}{dh}(g)*f\]

Answer 4

here f=(9+h)
g=sqrt(18-2h)
does that help ?

Answer 5

o...k...

Answer 6

is the derivative of 9+h=1?

Answer 7

exactly !

Answer 8

okay..!
thanks a lot! :)

Answer 9

you are welcome :)
