Question

A table top is semicircular in shape with diameter 2.8 m. Area of this table top is

(a) 3.08 m² (b) 6.16 m² (c) 12.32 m² (d) 24.64 m²

Answer 1

(a) 3.08 m²

From the question it is given that, diameter of semicircular shape = 2.8 m

So, radius of semicircular shape = 2.8/2 = 1.4 m

Then, area of semicircular shape of table top = πr²/2

= ((22/7) × 1.4 × 1.4)/2

= 3.08 m²
