Q. 14

Dinesh has made a pie-chart of the students of their class who want to play which game. He has taken length of radius of circle 3.5 cm, let us write by calculating the perimeter and area of each sector of circles.

Answer :

Given, radius of circle = 3.5cm


Now, Area of each quarter sector of the circle


Quarter sector means there is angle of 90° at the center of circle


Length of sector = (length of sector =)


Where r is the radius of circle


= 269.5 cm


Perimeter of quarter circle = length of sector + 2 × length of radius


= 269.5 + 7


= 276.5 cm


Area of sector = ( area of sector =)


Where r is the radius of the circle


= 471.62 cm2
