town M is 60 km from town N on bearing of \( 048^{\circ} \). Another town R is 80 km de south of M . Given that R lies on bearing of \( 200^{\circ} \) from P and 70 km from sing a scale of 1 cm to represent 10 km . Make an accurate drawing to show the position of the four towns. From the scale drawing determine; (i) The distance in km of R from M (ii) The bearing of R from M (iii) Calculate the area enclosed by MNPR in square kilometer

A square prism measuring 2 m by 2 m in base length and 5 m in height has a half-sphere attached to the top. What is the total surface area of this composite solid?

e) La somma e la differenza delle diagonali di un rombo misurano 126 cm e 18 cm . Calcola la misura del raggio della circonferenza inscritta nel rombo.

the area of \( \triangle A B C=12 \mathrm{~cm}^{2} \), then \( \left(b^{2}+c^{2}-a^{2}\right) \tan A=\cdots \) 12 (b) 24

In the opposite figure : \( \frac{\mathrm{BE}}{\mathrm{BC}}= \) \( \begin{array}{ll}\text { (a) } \frac{1}{2} & \text { (b) } 2 \\ \text { (c) } \frac{1}{3} & \text { (d) } 3\end{array} \)
