Find the area and perimeter of the circle with the following:
Diameter= 35 cm
उत्तर
Diameter= 2 r
`=> "r" = "diameter"/2 = 35/2 = 17.5` cm
Area of the drde = πr2
`= 22/7 xx 17.5 xx 17.5`
= 962.5 cm2
Perimeter of the circle = 2 π r
`= 2 xx 22/7 xx 17.5`
= 110 cm
Therefore, Area= 962.5 cm2 and Perimeter= 110 cm
