Question

A circle of radius 5 cm is cut out from a square piece of an aluminium sheet of side 10 cm. what is the area of the remaining aluminium sheet​

Answer 1

Step-by-step explanation:

area of aluminium sheet = 10×10 = 100 cm2

area of circle = πr2

3.14×5×5 = 78.5 cm2

area of remaining sheet = 100-78.5 = 21.5 cm2

Answer 2

area of aluminium sheet = 10×10 = 100 cm2

area of circle = πr2

3.14×5×5 = 78.5 cm2

area of remaining sheet = 100-78.5 = 21.5 cm2
