Question 1.

Three girls Ishita, Isha and Nisha are playing a game by standing on a circle of radius 20 m drawn in a park. Ishita throws a ball to Isha, Isha to Nisha and Nisha to Ishita. If the distance between Ishita and Isha and between Isha and Nisha is 24 m each, what is the distance between Ishita and Nisha. [NCERT]

Solution:

∵ Distance between Isha and Ishita and Ishita and Nisha is same

∴ RS = SM = 24 m

∴They are equidistant from the centre

In right ∆ORL,

OL² = OR² – RL²

Hence distance between Ishita and Nisha = 38.4 m

Question 2.

A circular park of radius 40 m is situated in a colony. Three beys Ankur, Amit and Anand are sitting at equal distance on its boundary each having a toy telephone in his hands to talk to each other. Find thelength of the string of each phone. [NCERT]

Solution:

Radius of circular park = 40 m

Ankur, Amit and Anand are sitting at equal distance to each other By joining them, an equilateral triangle ABC is formed produce BO to L which is perpendicular bisector of AC

∴ BL = 40 + 20 = 60 m (∵ O is centroid of ∆ABC also)

Let a be the side of ∆ABC

Hence the distance between each other = 40\(\sqrt { 3 } \) m
