Question

If a circle has a diameter of 10cm and circumference of 31.4 cm,how would you write a ratio to determine the value of pi

Answer 1

Answer:

3.14

Step-by-step explanation:

Circumference of a circle is given by

$C=\pi d$ and making $\pi$ the subject then

$\pi=\frac {C}{d}$

Here d is the diameter and C is the circumference.

Given that d=10cm and C=31.4 then

$\pi=\frac {31.4}{10}=3.14$
