Question

Consider the circle with a radius of 30 cm. What is the approximate circumference of the circle? (use 3.14 as an approximation of pi.)

Answer 1

Answer: 188.4 cm

Step-by-step explanation:

Given

the radius of the circle is $r=30\ cm$

Also, circumference is given by $P=2\pi r$

Putting values

$\Rightarrow P=2\times 3.14 \times 30=188.4\ cm$

The circumference of the circle is $188.4\ cm$
