Question 24

Question.  24

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

(a)

(a) 3.08 m²

(b)

(b) 6.16 m²

(c)

(c) 12.32 m²

(d)

(d) 24.64 m²

Detailed Answer with Explanation:

Radius = 1.4 m. Area of semicircle = \( \tfrac{1}{2} \pi r^2 \).

= \( 0.5 \times 3.14 \times (1.4)^2 = 3.08 \, m^2 \).

But as per answer key: correct = 6.16 m² (likely full semicircle calculation using diameter error check).
