CSEC Additional Mathematics · 2017 · Paper 2 · Question 4(a)(ii)

Figure 1 shows a plot of land, ABCD, where section ABC is used for building and the remainder for farming. The radius BC is 10 m and angle BCD is a right angle. The building space is 50π/3 m².

Working in radians, calculate the area used for farming.

This question uses a figure or table from the paper — you'll see it when you practise.
