Answer:
The radius of circle is 10.5 units
D is correct
Step-by-step explanation:
We are given a circle with centre M
We need to find the radius of circle.
Radius: It is distance from centre to a point on circle.
In figure,
Center at M
Points on circle, R and S
Radius should be RM, SM
From figure,
RM=10.5 units
SM=10.5 units
RM=SM=10.5 units
Hence, The radius of circle is 10.5 units
