Q. A circle has a diameter of 14 m. What is its area? (Use π = 3.14)
A.
153.86 m²
B.
154 m²
C.
150 m²
D.
160 m²
Solution
Radius = diameter / 2 = 14 m / 2 = 7 m. Area = π × radius² = 3.14 × (7 m)² = 3.14 × 49 m² = 153.86 m².
Q. What is the area of a square inscribed in a circle of radius 10 cm?
A.
100 cm²
B.
200 cm²
C.
150 cm²
D.
50 cm²
Solution
The diagonal of the square is equal to the diameter of the circle, which is 20 cm. Side of the square = diagonal / √2 = 20 cm / √2 = 10√2 cm. Area = (10√2 cm)² = 200 cm².
