Answer» Radius of circle = 1/2 * Diameter of circleRadius = 1/2 *14= 7 cm 7 cm is the best answer Given diameter=14. radius r =14/2=7 angle subtended=21= [14+7]= 21×π/180=π/8.57....then length of arc= r×teetta=21×π/8.57..= 21π/8.57 ie, length of arc =21π/8.57.. radius circle=1/2 diameter circle Radius = 1/2 × 14=7 cm

SOLVED EXAMPLES1) The diameter of a circle is 14 cm. Findlength of the arc, subtending an angle ofat the centre.

Answer»

Radius of circle = 1/2 * Diameter of circleRadius = 1/2 *14= 7 cm

7 cm is the best answer

Given diameter=14. radius r =14/2=7 angle subtended=21= [14+7]= 21×π/180=π/8.57....then length of arc= r×teetta=21×π/8.57..= 21π/8.57

ie, length of arc =21π/8.57..

radius circle=1/2 diameter circle Radius = 1/2 × 14=7 cm
