Area of a circle = πr2
Area of a semicircle = \frac { 1 }{ 2 } πr2
Area of quadrant = \frac { 1 }{ 4 } πr2.Area of a circle = π r. Length of an arc of a sector of a circle with radius r and angle with degree measure θ is= theta/360 *2*π *r. Area of a sector of a circle with radius r and angle with degree measure θ is theta/360 *π*r.
