Anybody had unexpected results in 2016 Math D?
Also, anybody has access to May/June 2016 Math D question paper?
Thanks.
how to do the highlighted question?
Voulme of cylinder = pi r^2 h
thanksVoulme of cylinder = pi r^2 h
Volume of outter cylinder(VO) = pi (3.5 + r)^2 (20)
volume of inner cylider (VI)= pi r^2 (20)
Volume of solid = VO - VI
3000 = VO - VI
Solve for r
r = 5.07
Post the question. We will see where we can help u.can anybody please explain questions related to upperbond and lowerbond
No pblmthank you so much
You cant use cos rule here. How to solve without that.
But y can't v use it? It's not written in the question that v can not use itYou cant use cos rule here. How to solve without that.
I mean yes we can use it here. I'm looking for a way to solve without it.But y can't v use it? It's not written in the question that v can not use it

For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
