The circumference of a circle is measured as 28cm with an error of 0.01cm. The percentage error in the area is

Explanation

To solve the problem of finding the percentage error in the area of a circle given the circumference and its error, we can follow these steps:

### Step 1: Understand the relationship between circumference and radius
The circumference \( C \) of a circle is given by the formula:
\[ C = 2\pi r \]
where \( r \) is the radius of the circle.
