Answer: 
Step-by-step explanation:
The formula for the lateral area of a cone
is:

Where:
is the radius of the circular base of the cone
As we know its diameter
, its radius is 
is the height of the cone

2.12=2.120 that is the answer
Answer:(a) n=0.233
Step-by-step explanation:
Given
We Know according to Taylor tool life

V=cutting speed
T=tool life
n=tool life exponent
c=constant



taking log both side

n=0.233
