The AWNSER to the question is .3
Answer:
132 cm
Step-by-step explanation:
The diameter of the circle is 42 cm. A circle's radius is half of its diameter, hence, its radius is:
42 / 2 = 21 cm
The circumference of a circle is the total length of the circle and it is given as:
![C = 2\pi r](https://tex.z-dn.net/?f=C%20%3D%202%5Cpi%20r)
where ![\pi = \frac {22} {7}](https://tex.z-dn.net/?f=%5Cpi%20%3D%20%5Cfrac%20%7B22%7D%20%7B7%7D)
r = radius of the circle
Hence, the circumference of the circle is:
![C = 2 * \pi * 21\\C = 132 cm](https://tex.z-dn.net/?f=C%20%3D%202%20%2A%20%5Cpi%20%2A%2021%5C%5CC%20%3D%20132%20cm)
