Question

a paper form a rectangle pqrs in which pq 20 cm qr 7cm two semi circular as diameter cut off find the area of remaining part​

Answer 1

Answer:

Area of remaining Part=140-38.5

=101.5cm^2

Step-by-step explanation:

Area of rectangle= pq×qr

=20×7

=140cm^2

Area of two semi circles=Area of one complete circle

=

$\pi \: r {}^{2}$

=(22/7)(7/2)(7/2)

=11×3.5

=38.5cm^2

Area of remaining Part=150-38.5

=101.5cm^2
