Question
The ratio between the area of a square and that of a
circle, when the length of a side of the square is equal to that of the diameter of the circle, is (take π = 22/7)Solution
Let the diameter of the circle and sides of the square be 14 cm, then  The radius of the circle r = 14/2 = 7 cm Side of the square a = 14 cm As we know, Area of square = a² Area of circle = πr² Ratio of area of the square to that of circle = 142: 22/7 × 7 × 7  = 14:11
A triangle has sides 7 cm, 24 cm, and 25 cm. Determine the largest angle in the triangle.
