I hope this helps you
Volume of cone =1/3.pi.r^2.h
Volume of cone =1/3.3,14.6^2.9
Volume of cone =339.12
The formula for direct variation is y = kx<span> where k </span>≠ 0
y = 9/x is an inverse relation
Use math induction proof method will be usefully
for n=1 will get
1^2 = 1(6*1^2 -3*1 -1)/2
1 = 1(6-4)/2
1 = 1(2)/2
1 = 1
suppose true for n=k and prove for k = k+1
hope this will help you
