Answer:
Step-by-step explanation:
From a circular card sheet of radius 14 cm, two circles of radius 3.5 cm and a rectangle of length 3 cm and breadth 1 cm are removed, (as shown in the given figure below). The area of the remaining sheet is 536 cm2.
area of sheet=πr=22/7x 14x14 (now cancel 14 by 7 and instead of 14 write 2)
=22x2x14
=616 cm
area of small circle=2xπx3.5x3.5
=77cm2
area of rectangle=3x1
=3
remaining area=616-(77+3)
=536 cm2
simply the answer is (536)
