Examples on Square 1 to 20
Example #1: If a circular tabletop has a radius of 8 inches. Calculate the area of the tabletop in sq. inches?
Solution:
Area of circular tabletop(A) = πr2 = π (8)2
Using values from square 1 to 20 chart;
i.e. A = 8 x 8 x π = 64π
As we know pi(π)= 3.14
Therefore, the area of the tabletop = 200.96 inches2.
Example 2: Calculate the area of a square window whose side length is 15 inches
Solution:
Area of square window (A) = Side2
A = 152 = 15 x 15 = 225
S0, the area of a square window is 225 inches2.
