How to Find the Slope in a Circle?

Answer It is difficult to find the slope of a point on a circle because there is no explicit function for a complete circle. The implicit equation x^2 + y^2 = r^2 results in a circle with a center at the ... Read More »

Top Q&A For: How to Find the Slope in a Circle

A circle is 2106 sq ft. find the radius of the circle to the nearest foot (use 3.14 for pi)?

Since area = r*r*pi, and we want to find the radius, let's set this up like an equation, using r as the variable that represents the radius (and the value we're looking for). Let's also write it as... Read More »
