Linear Approximate the change in the lateral surface area (excluding the area of the base) of a right circular cone with a fixed height *h*=6*m* when its radius decreases from r=10m to r=9.9*m* (S=pi x r (square root of r^{2 }+h^{2)}

Step 1

We have

Step 2

First find the differentiation of lateral surface area with respect to r.

Step 3

Now substitute dr = – 0.1...
