Circle $C$ has radius 10 cm. How many square centimeters are in the area of the largest possible inscribed triangle having one side as a diameter of circle $C$?
A = 1/4(2r)2 cm²
Isoceles triangle base = 10 height would be 5
1/2 * 10 * 5 = ......... cm2
the base is not 10; it's 20 So, area = 102 cm2
Base = 20
Height = 10
Area = 1/2 base * height = 1/2 * 20 * 10 = .........units 2
