Question

A circle of radius 3 cm is cut out from a square piece of paper sheet of side 8 cm. What is the remaining area of sheet ? (Take π = 3.14)

Answer 1

Answer:

Step-by-step explanation:

Radius = r = 3cm

Area of the circle = πr^(2)

= 3.14×3^(2)

= 3.14 × 9

=28.26 sq cm........(1)

Now side of square = s = 8cm

Area of the square sheet = s×s

= 8×8

= 64 sq cm........(2)

Area of the remaining sheet = (area of square sheet) - (area of circle)

=(64 - 28.26) sq cm

=53.74 sq cm

Answer 2

area of remaining sheet=area of square-

area of circle

=side^2-pie×r^2

=8^2-3.14×3×3

=64-28.26

=35.74

i hope it help you
