Question

The minute hand of a clock is $14cm$ long. How much distance does the end of the minute hand travel in $15$ minutes? $(\pi =\frac{22}{7})$

• A. $11cm$
• B. $22cm$
• C. $33cm$
• D. $44cm$

Answer 1

The correct option is B $22cm$

Distance travelled by the minute hand in $15minutes$
$=\frac{1}{4}$ of the circumference of the circle of radius $14cm$
$=(\frac{1}{4}\times 2\times \frac{22}{7}\times 4)cm=22cm$
