Question

Column I represent the radius of different circles. Match with their respective diameters in Column II.

• A. $14$
• B. $16$
• C. $8$
• D. $4$

Answer 1

Diameter of a circle is two times the radius, d = 2r

When radius is $7,$ diameter $=2\times 7=14$
When radius is $2,$ diameter $=2\times 2=4$
When radius is $4,$ diameter $=2\times 4=8$
When radius is $8,$ diameter $=2\times 8=16$
