उत्तर
A table top is semicircular in shape with diameter 2.8 m. Area of this table top is `bb(underline(3.08 m^2))`.
Explanation:
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 tablet top = `(πr^2)/2`
= `((22/7) xx 1.4 xx 1.4)/2`
= 3.08 m2
