\( 1^{\circ} \) a) Write \( \widehat{x O z} \) using \( \widehat{x O y} \) and b) Write \( \widehat{y O I} \) using \( \widehat{y O z} \) and c) Show that \( \widehat{x O z}=\widehat{y O t} \).

SULrt \( 5 \quad \) Sebuah mesin memproses minuman mengeluarkan \( 62.92 \mathrm{~m}^{3} \) minuman schari daripada sebuah tangki. Tangki itu mempunyai jejari 2.2 m dan tinggi 4 m . Diberi bahawa isipadu tangki, \( V \) berubah secara langsung dengan kuasa dua jejari, \( j \mathrm{~m} \) dan tinggi, \( t \mathrm{~m} \). A beverage processing machine produces \( 62.92 \mathrm{~m}^{3} \) of beverage per day from a tank. The tank has a radius of 2.2 m and a height of 4 m. Given that the volume of the tank, \( V \) varies directly with the square of the radius, \( j \) mand the height, \( t \mathrm{~m} \). (a) Ungkapkan \( V \) dalam sebutan \( j \) dan \( t \). Express \( V \) in terms of \( j \) and \( t \).
