Figure 2 shows a plan view of a semicircular garden \(A B C D E O A\)
The semicircle has
- centre \(O\)
- diameter \(A O E\)
- radius 3 m
The straight line \(B D\) is parallel to \(A E\) and angle \(B O A\) is 0.7 radians.
- Show that, to 4 significant figures, angle \(B O D\) is 1.742 radians.
The flowerbed \(R\), shown shaded in Figure 2, is bounded by \(B D\) and the arc \(B C D\).
- Find the area of the flowerbed, giving your answer in square metres to one decimal place.
- Find the perimeter of the flowerbed, giving your answer in metres to one decimal place.
