The maximum area the cow can gaze is 1256 square feet
<em><u>Solution:</u></em>
Given that a cow is tethered with a rope 20 feet long
<em><u>To find: Maximum area the cow can graze</u></em>
The maximum area the cow can gaze is the area of the circle with radius 20 feet
<em><u>The area of circle is given as:</u></em>
Where, "r" is the radius of circle and is a constant equal to 3.14
<em><u>Substituting the values in above formula we get,</u></em>
Thus the maximum area the cow can gaze is 1256 square feet
5-(-8)= 5+8= 13 because when the problem is subtraction you change the last number to a positive or negative
