Question

pls tell me the answer urgently... step by step pls​

Answer 1

Answer:

26

Step-by-step explanation:

Area of the rectangle is A=lxb

Area of the circle is=πr2

Area of the shaded part =area of the rectangle -area of the circle

=lxb-πr2

=18x10-22/7x7x7

=180-154

=26

Answer 2

Step-by-step explanation:

Given

Radius (r) = 7cm

length of rectangle PQRS = PQ =18 cm

Breadth of rectangle PQRS = QR = 10 cm

Area of rectangle PQRS = Length × Breadth

=PQ × QR

=18cm × 10cm

=180cm^2 ( centimetre square)

Area of Circles = πr^2

=22/7 × 7 × 7

= 154cm^2

Area of Shaded portion = Area of rectangle PQRS - Area of Circle

=

$180 - 154 = 26cm ^{2}$
