Answer:
Step-by-step explanation:
Mathematically, the area of a sector can be calculated using the formula below;
area of sector = angle/360 * pi * r^2
From the question, angle = 180
pi= 22/7
r = d/2 = 5.6cm/2 = 2.8 cm
So the area of the sector is as follows;
A = 180/360 * 22/7 * 2.8^2
A = 2 * 22/7 * 2.8^2 = 49.28
which is 49.3 cm^2 to the nearest tenth
