Question

Can some one plz help me

Answer 1

Given,

Diameter of circle = 6 in.

As we know that radius is half of diameter.

Radius = 6 × 1/2 = 3 inches

Now,

`\sf Circumference \: of \: circle = 2 \pi \: r`

`= \: 2 * (22)/(7) * 3`

`= (44)/(7) * 3`

`= (132)/(7)`

`= 18.84\: in.`

Hence,option ( a ) is correct.

Answer 2

Explanation:

6 times 3.14 is 18.84
