The length of the minute hand clock is 7cm find the distance does cover in one hour
Answers
Step-by-step explanation:
Radius = 7 cm.
Angle covered in one hour = 360° (A full rotation)
Therefore, area covered will be equal to the area of the circle, and the circumference will also be equal.
So,
Circumference = 2πr = 2×22/7×7
Cancel both sevens, and you'll get 2×22
= 44 cm
Area = πr² = 22/7×7×7
Cancel two sevens, and you will get 7×22
= 154 cm²
Hope it helps!
