A tapered bar is 10.0 inches long. The diameter of the circular cross section decreases linearly from 4.0 inches at one end to 2.0 inches at the other end. Determine the equation that expresses the cross-sectional area of the bar as a function of the position, x, along the length. the area of a circle is given by A=pi r^

answer: plz give a pic and answer choices so i can answer!

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
