Question

A cow is tethered with a rope 20 ft long. What is the maximum area the cow can graze?​

Answer 1

The maximum area the cow can gaze is 1256 square feet

Solution:

Given that a cow is tethered with a rope 20 feet long

To find: Maximum area the cow can graze

The maximum area the cow can gaze is the area of the circle with radius 20 feet

The area of circle is given as:

$area = \pi r^2$

Where, "r" is the radius of circle and $\pi$ is a constant equal to 3.14

Substituting the values in above formula we get,

$area = 3.14 \times 20^2\\\\area = 3.14 \times 400\\\\area = 1256$

Thus the maximum area the cow can gaze is 1256 square feet
