The radius and height of a solid cylinder is 8 cm and 14 cm respectively. Find, correct to two d.p the total surface area.
(Take \(\pi = \frac{22}{7})\)

Find the value of a in the equation: cos (a + 14)° = sin (4a + 6)°

The radius of a sphere is 3 cm. Find, in terms of π, its volume.

m:n = \(2\frac{1}{3} : 1\frac{1}{5}\) and n : q = \(1\frac{1}{2} : 1\frac{1}{3}\), find q : m.
