Answer:
143.7cm^2
Step-by-step explanation:
Given data
Volume= 576cm^3
Radius= 8cm
The expression for the volume of cylinder is
V= πr^2h
substitute
576= 3.142*8^2*h
576= 3.142*64*h
576= 201.088h
h= 576/201.088
h=2.86cm
The formula for finding the lateral area of a right circular cylinder is:
A=2πrh
substitute
A= 2*3.142*8*2.86
A= 143.7cm^2
Hence the area is 143.7cm^2
Answer:
389
Step-by-step explanation:
3*118 + 35
It can be solved by factoring or taking the root of both sides.
x= 2 radical 3. and -2 radical 3
Take the common out of both numerator and denominator and cancel out the terms which are equal.
(8x³ - 2x² - 3x)/(12x²- 9x)
= x(8x² - 2x -3)/3x(4x - 3)
= (8x² - 2x -3)/3(4x - 3)
=(4x-3)(2x+1)/3(4x-3)
= (2x+1)/3
