The radius of a circle is given as 10cm subject to an error of 0.2cm. the error in the area of the circle is?

12.56 is the error in area of circle.

Step-by-step explanation:

Given that:

Radius of the circle, r = 10 cm

Error in measurement of radius, = 0.2 cm

To find:

The error in area of circle = ?

Solution:

First of all, let us have a look at the percentage error in measurement of radius:

Now, we know that Area of a circle is given as:

Area according to r = 10

Now, error in area = 4% of 314

So, the answer is:

12.56 is the error in area of circle.
