Question

What is the diameter of a circle whose radius is 11 ?

Answer 1

Hint: Here in this question we have been asked to find the diameter of a circle whose radius is given as 11 for answering this question we will use the concept that we had learnt during the concept of circles which says that the diameter of a circle is given as twice the given radius of the circle.

Complete step by step answer:
Now considering the question we have been asked to find the diameter of a circle whose radius is given as 11 .
During learning the basic concepts of circle we have learnt that that the diameter of a circle is given as twice the given radius of the circle.
Hence we can say that the diameter of the circle in this case will be given as $2\times 11$ .
Here below we have shown the diagram of the circle with its radius and diameter showing separately.

Therefore we can conclude that the diameter of a circle whose radius is given as 11 will be given as 22.

Note: During answering questions of this type very few mistakes are possible. This type of easy and simple question can be answered in a short span of time accurately. Someone can make a calculation mistake in a hurry like considering the following calculation $2+11=13$ as correct which will lead them to end up having a wrong conclusion.
