The circumference of a circle is `31.4 cm.` Find the radius and the area of the circle ? (Take `pi=3.14`)

Explanation

To solve the problem, we need to find the radius and the area of the circle given its circumference. Here are the steps:

### Step 1: Write down the formula for the circumference of a circle.
The formula for the circumference (C) of a circle is given by:
\[ C = 2 \pi r \]
where \( r \) is the radius and \( \pi \) is approximately 3.14.

### Step 2: Substitute the given circumference into the formula.
