Question

An old man goes for morning walk on a semi-circular track of radius $28\text{m}$, if he starts from one end of the track and reaches to other end, the distance covered by the man will be
(Take $\pi =\frac{22}{7}$)

• A. $80\text{m}$
• B. $75\text{m}$
• C. $88\text{m}$
• D. $68\text{m}$

Answer 1

The correct option is C $88\text{m}$

Distance covered by the man will be the length of the semi-circular track i.e. $D=\pi r=\frac{22}{7}\times 28=88\text{m}$
