Question

3. Kamalesh has a dining table, circular in shape of radius 70 cm
has a circular quadrant dining table of radius 140 cm Whose dining
a greater area, (7 - 22/7)?​

Answer 1

Answer:

They are equal.....

Step-by-step explanation:

Area of a circle=πr²           π=22/7

Area of a quadrant of a circle=πr²/4

Area of the circular table=22/7 x 70 x70=220x70=15400cm²

Area of circular quadrant table=22/7 x 140 x 140/4=22 x 20 x 140/4=22x5x140=22x700=15400cm²

Thus the dining area of both of them are equal

and area of quadrant is πr²/4 because quadrant is ¹/₄ of a circle.
