Question

hour and minute hand of a clock at 3.5 cm and 4.9 cm long respectively find the sum of the area covered by the hands in one day​

Answer 1

Answer:

area covered by the hour hand = π × r²

= 22/7 × 3.5²

= 38.5

area covered by the minute hand = π × r²

= 22/7 × 4.9²

= 75.46

total area = 38.5 + 75.46 = 113.96cm²
