Question

An ox is tied to a pole situated at the center of a field, with a 10 m long rope. The ox moves keeping the rope tight. Find the area of the ground swept by the rope.( Use $\pi =3.14$)

• A. $31.4m^2$
• B. $614m^2$
• C. $314m^2$
• D. $416m^2$

Answer 1

The correct option is C $314m^2$

The area swept will be equal to the area of circle which can be drawn taking pole as centre and radius as length of rope.

Area of circle $=\pi r^2$

= $3.14\times {10}^2$ = 314 $m^2$.
