Question

(a) Calculate the volume of a cylinder with radius 30 cm and height 50 cm. [2]
A cylindrical tank, radius 30 cm and length 50 cm, lies on its side. It is partially filled with water. The shaded segment AXBY in the diagram shows the cross-section of the water. The greatest depth, XY, is 12 cm. OA # OB#30 cm. (i) Write down the length of OX. [1] (ii) Calculate the angle AOB correct to two decimal places, showing all your working
