For the following questions answer them individually
Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R
Assertion A : If the volumes of two cubes are in the ratio of 3 : 2 : 7 then their surface areas are in the ratio of 4 : 9.
Reason R : If the surface areas of two cubes are in the ratio $$S_{1} : S_{2}$$, then their volumes are in the ratio $$S_{1}^{2/3} : S_{2}^{2/3}$$
In the light of the above statements, choose the correct answer from the options given below :
If the high and base radius of a cone are increased by 50% and 25% respectively then the ratio between the volume of a given cone and the new cone is
If one root of quadratic equation $$2x^{2} - 3x + (2k + 1) = 0$$ is five times the other then the value of k is :
If $$(f) = t^{2}$$, compute f(99) and f(101), Between those times, what is the increase in f divided by the increase in t?
When you jump up and fall back your height is $$y = 2t - t^{2}$$. Find the time in the air and maximum height.
What would be the area bounded by the curves $$y = \sqrt{(4-x^{2})}: x^{2} = -\sqrt{(2y)}$$ and $$x = y$$
