7th question ans will be C
if n= constant or pie

1/3 * n * (2r)^2 * 2h = 8/3*n* r*h = A
8*(cylinder A volume) =B

both the values are equal so answer is C

Hi devineni,

For the forth one, i equated the angle of both the triangle, so that makes it
k/x = (a-k)/(b-x)

Solving this you can find the answer.
P.S: 'x' is the value of x-coordinate.

For the Seventh one,
The volume of cylinder is (pie*r^2*h), for cone is 1/3*(pie*r^2*h)

For the 8th one,
No one side of the triangle is greater than sum of 2 other sides, Hence the side AC is <9.
That makes it lesser than other 2 angles of triangle ABC.
which means <60

Cheers
