Question : What is the area of a circle with a diameter of $12~ ext{mm}$?

Option 1: $12 \pi~{ ext{mm}}^2$

Option 2: $24 \pi~{ ext{mm}}^2$

Option 3: $36 \pi~{ ext{mm}}^2$

Option 4: $48 \pi~{ ext{mm}}^2$

Team Careers360 · Accepted Answer

Correct Answer: $36 \pi~{ ext{mm}}^2$

Solution : Given: The diameter of the circle = $12~ ext{mm}$
So, the radius($r$) = $\frac{12}{2}$ = $6~ ext{mm}$
We know that the area of a circle = $\pi r^2$
= $\pi×6×6$
= $36\pi~ ext{mm}^2$
Hence, the correct answer is $36\pi~ ext{mm}^2$.
