Answer 1

○=> Correct option :

$\color{plum}\tt\bold{(B)}$

○=> Steps to derive correct option :

We know that :

$\color{hotpink} \tt \: circumference \: of \: a \: circle\color{plum} = 2\pi r$

So, let the diameter of this circle be x.

Which means :

$=\tt2 \times \pi \times r$

$=\tt 2 \times x \times \pi = 12\pi$

$=\tt 2x\pi = 12\pi$

$=\tt x = \frac{12}{2}$

$= \tt \: x = 6 \: m$

Thus, the radius of the circle Robert drew = 6 m

Since the circle in option B has a radius of 6 m, it is the circle Robert drew.

▪︎Therefore, the correct option is (B)
