To find the third side of a triangle (there are two answers you could get), you need to use the Pythagorean formula: a^2+b^2=c^2.  First answer, 20^2+30^2=c^2.  Solve for c.  c=36.06.  The second answer, 20^2+b^2=30^2.  Solve for b.  b=26.36.

222.51 (when rounded)

Step-by-step explanation:

Pi x r squared is the formula to find the area of a circle

= 222.51

You basically find the area of each circle by find their diameters. So half of the length shown on each circle.

divide both sides by 2 2x/2=10/2

simplfy and you get x=5

To find the y-intercept: replace x with 0
to find the x-intercept: replace y with 0

x-int:
0 = 10x - 32
32 = 10x
x = 3.2
(3.2, 0)
y-int:
y = 10(0) - 32
y = -32
(0, -32)
