Question

Figure out the area covered by a 7 cm long minute arm in 5 minutes of time.

Answer 1

Step-by-step explanation:

total part of the circle = 5/60 = 1/12

area of the whole circle = πr×r = 22/7 × 7× 7

area of the whole circle covered by minute arm

= 154 cm^2

area covered by minute arm in 5min = 154×1/12

= 77/6cm^2
