Approximating changes Approximate the change in the lateral surface area (excluding the area of the base) of a right circular cone of fixed height of ?h? = 6 m when its radius decreases from ?r =10 m to ?r? = 9.9 m S = ?r ? + h .2

Solution 27E STEP 1 According to the approximation formula we can write f(x + x) f(x) = f(x).x f = f(x).x, Where f is the function,x is the variable and x is the change in x. STEP 2 Therefore according to this question, we have to approximate the change in the lateral surface area of a right circular cone of fixed height(h) and its radius(r) decreases from 10m to 9.9m. STEP 3 The lateral surface area of a right circular cone...
