Question

Find the following measure for this figure.

Circumference of circle =

12pi units
24pi units
36pi units

Answer 1

We use the formula: Circumference of circle = 2πR

R = 6 units

C = 2πR = 2 × π × 6 = 12π units

Correct ansver: a) 12π units

Answer 2

The correct option is 1. The circumference of circle is 12π units.

Explanation:

From the given figure it is clear that the radius of the circle is6 units.

The circumference of a circle is

`C=2\pi r`

Where, r is the radius of the circle.

The circumference of the circle is

`C=2\pi (6)`

`C=12\pi`

The circumference of circle is 12π units.

Therefore option 1 is correct.
