Question

O
From a circular card sheet of radius 18 cm, two circles of radius 2.5 cm and a
rectangle of length 1.5 cm and breadth 1 cm are removed. Find the area of the
remaining sheet. Take n =22/7
​

Answer 1

Step-by-step explanation:

area of 2 circles = 2(22/7)(2.5)(2.5)

= 275/7 cm²

area of card = (22/7)(18)(18)

= 7128/7cm ²

area of rectangle= 1.5(1)

= 1.5cm²

area of remaining sheet= 7128/7-(275/7+1.5)

= 7128/7-(264.5/7)

= (6917.5/7) cm2
