A section of stained glass is made by placing a circle at the top of a triangle with a base of 10 centimeters and a height of 8 centimeters. The diameter of the circle is equal to the height of the triangle. What is the area of the section of stained glass? Show your work. Use Pi = 3,14

  1. Reiny

    So basically all we need is the area of the triangle plus the area of the circle.
    area = (1/2)(10)(8) + π(4)^2
    = 40 + 16π
    = ......

    you do the arithmetic
