The acres for rice, pineapple, cassava, cocoa and palm oil in a certain district are given respectively as 2, 5, 3, 11 and 9. What is the angle of the sector of cassava in a pie chart? 

A.

180\(^o\)

B.

36\(^o\)

C.

60\(^o\)

D.

108\(^o\)

Correct answer is B

Total number of acres = 2 + 5 + 3 + 11 + 9 = 30

The angle of acres = 2 + 5 + 3 + 11 + 9 = 30

The angle of the sector for cassava in a pie chart = \(\frac{3}{30} \times 360^o = 36^o\)
