SA = ?
<span>r = 2x - 1 </span>
<span>h = 3x </span>
<span>Then, </span>
<span>SA = 2π(2x - 1)² + 2π(2x - 1)(3x) </span>
<span>==> 2π(4x² - 4x + 1) + 6πx(2x - 1) </span>
<span>==> 8πx² - 8πx + 2π + 12πx² - 6πx </span>
<span>==> 20πx² - 14πx + 2π units² </span>
A straight Part of a liine that has no endpoints is life, it is boring and you know its going to come to an end :) no problem w the poetry help
Answer:
Step-by-step explanation:
a^2+b^2=400
a^2=400-b^2
a=sqrt(400-b^2) & -sqrt(400-b^2)
-----------------------------------------------
b^2=400-a^2
b=sqrt(400-a^2) & -sqrt(400-a^2)
