A circular bread has radius 14 cm. If 40% is eaten, what is the remaining area? (Use π = 22/7)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 369.6 cm2
Area of circle = π × r × r
Radius r = 14
Area of circle = 22/7 × 14 × 14
= 22/7 × 196
= 4312/7
40% is eaten, so remaining area = 60% of total area
Remaining area = 60/100 × 4312/7
= 3/5 × 4312/7
= 12936/35 = 369.6
