(b)1 : 1
(c)cannot be determined
Q6. A right circular cylinder is formed. Ratio of total surface area of the cylinder to its total curved surface area is 4 : 3. If volume of the cylinder is 25872 cm3 then find the total surface area(in cm2) of cylinder ?
Q8. What is the minimum value of function
Q10.The maximum length of a pencil that can be kept in a rectangular box of dimensions 8 cm × 6 cm × 2 cm, is
(a) 2 √13 cm
(b) 2 √14 cm
(c) 2 √26 cm
(d) 10 √2 cm
S1. Ans. (c)
As area of ∆QTR cannot be determined hence the required ratio cannot be determined.
