Area of a circle = pi *r^2
A = 3.14 * 5^2
A = 78.5

Area of rectangle = L * W
20 x 14 = 280

280 - 78.5 = 201.5 <===

Can someone explain to me how to do this?
elena55 [62]
In the slope intercept form equation of a line (y=ax+b) a represents the slope, and b represents the intercept, which is -5. Thus, we know y=ax-5. The slope can be found by creating a fraction with the change in y value on top, and the change of x value on the bottom. If we have two points (4, 1) and (0, -5) we can put this into a fraction - \frac{-5-1}{0-4}, which simplifies down to -6/-4, or 3/2. Thus the answer is f(x)=\frac{3}{2}x-5<span />
