## Squares 1 to 20 Chart

Here is the squares 1 to 20 Chart: ## 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.
