Question

Alex covers 50 m from B to point A. What is the shortest distance (in m) that Shalini​ should cover to reach A from the center O?​

• A. 100
• B. 75
• C. 50
• D. 25

Answer 1

The correct option is D 25

We know that the distance between center and any point on the boundary of the circle is same and is called radius.
From B to A = 50 m
OA and OB will be the radius of the circle.
OA + OB = 50 m
Radius + Radius = 50 m
Radius = $50÷2$
= 25 m
Now Shalini should cover OA distance that is again the radius of the circle.
Hence, Shalini needs to cover 25 m
