Question

3. A quarter circle is drawn at each corner
of the square (Fig. 15.31). Find the area
of the shaded portion (take it = 3.14).
30 m
Fig. 15.31​

Answer 1

Answer:

193.5 m^2

Step-by-step explanation:

If the sides of the square is 30 m.

radius = 30/2 = 15m

4 quarter circles make a full circle,

Area of circle = πr^2

=3.14×15×15

=706.5 m^2

Area of square = (side) ^2

=(30)^2

=900 m^2

Area of shaded region = 900-706.5

=193.5 m^2
