Question

The figures in the rectangle are $8$ identical quadrants. What is the area of the shaded part? $(Take\pi =3.14)$

• A. $22.52c{m}^2$
• B. $15.48c{m}^2$
• C. $56.52c{m}^2$
• D. $28.36c{m}^2$

Answer 1

The correct option is B $15.48c{m}^2$

$8$ identical quadrants $=2$ circles of radius $3cm$ each.

$\therefore$ Area of shaded part $=$ Area of rectangle $-$ Area of 2 circles

$=12\times 6-2\times 3.14\times 3\times 3$

$=72-56.52$

$=15.48c{m}^2$
