**how do you find the approximate uncertainty of a circle of radius 3.8x10^4?**

## Homework Statement

how do you find the approx uncertainty for a circle with radius 3.8x10^4, i have no idea how to get the final uncertainty of the circle the radius uncertainty is 0.1x10^4

area of a circle is pie*r^2? so that means the area of the circle should be 4.5x10^9 isn't it?
