Question

An ox is tied to a pole situated at the centre 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 π = 3.14)

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

Answer 1

The correct option is C $314m^2$

We know that the area swept by the rope will be circular in shape.

Given, radius of the circle thus formed (length of the rope) = 10 m

Area swept by the rope $=\pi r^2$
(where r is the radius of the circle)

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