- (A) Calculate AC and angle ACB . Hence calculate AD .
(B) Calculate the area of the garden. - The shape of the fence panels used in the garden is shown in Fig. 10.2. EH is the arc of a sector of a circle with centre at the midpoint, M , of side FG , and sector angle 1.1 radians, as shown. \(\mathrm { FG } = 1.8 \mathrm {~m}\).
