Question

The radius of a circle P measures half the radius of circle Q. The diameter of circle Q measures 6 meters. What is the length of the diameter of circle P.

Answer 1

Answer= 3

Explanation- If the diameter of Q is 6, then we want to cut that in half to make radius. Half of 6 is 3 so, to make the radius of P we need to cut 3 in half which would be 1.5 and if the diameter is 2r, 2 times 1.5 equals 3.

Answer 2

3 meters

Explanation:

We are told that ...

the radius of circle P is half the radius of circle Q.

The same relation applies to any corresponding linear measures of these circles, so we can also say ...

the diameter of circle P is half the diameter of circle Q

the diameter of circle P is half of 6 meters, so is 3 meters
