Susan is making a small cone out of paper. The cone has a radius of 13.2cm, and the angle between the lateral surface and the base is 38.6degrees. The formula for the lateral area, s, of a cone is a=pie, where r is the radius and l is the slant height. What is the cones approximate layers area?

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
