Question
The diameter of the base of a cylindrical vessel is 30
cm and its height is 56 cm. Find its curved surface area (in cm²).Solution
Curved surface area = 2 πrh Given Diameter = 30 cm, so radius r = 15 cm Height h = 56 cm Substitute these values: CSA = 2 × 15 × 56 π CSA =1680 π Approximating π as 22/7 CSA= 1680 × 22/7 =240×22=5280cm²

6x + 8y - [(12x + 6y) - (4x + 3y) + 2y] - 4xIf 9x2 + 16y2 = 24xy, then find the ratio of ‘x’ and ‘y’, respectively.
- Suppose [a + (1/16a)] = 3, then the value of [16a³ + (1/256a³)] is:
If, 6x + y = 20, and 2xy = 32, and 6x > y, then find the value of 216x³ – y³.
If x + 1/x = 2, find x⁷ + 1/x⁷.
(x – 6) 2 + (y + 2) 2 + (z – 4) 2 = 0, then find the value of 4x - 3y + z.
