From a squaremetal sheet of side 28 cm a circular sheet an be cut find the area of remaining sheet
Answers
Answer:
168 cm2
Step-by-step explanation:
square metal sheet side a = 28 cm
then Area of square metal sheet = a x a
= 28 x 28 = 784 cm2
If we cut the square metal sheet in circular form then..
diameter is equal to side of metal sheet
so.....
diameter = 28 cm
Radius = 14 cm
Area of circular sheet is = Pi r x r
= (22/7 ) x 14 X 14
= 616 cm2
Remaining Area of metal sheet =
Area of square metal sheet - Area of circular sheet
= 784 - 616
= 168 cm2
