Question

a circle of radius 2.1 centimetre is cut out from a square piece of plastic sheet of side 7 cm what is the area of the leftover plastic sheet​

Answer 1

=======....=======35.15

Answer 2

Area of square = side × side

= 7 × 7

= 49 cm² —(equation 1)

Area of Circle = πr²

= 22/7 × 2.1 × 2.1

= 13.86 cm² —(equation 2)

Area of leftover = (equation 1) - (equation 2)

= 49 - 13.86

= 35.14 cm² ans.
