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
In lowest terms the answer would be 8 1/3

Applyin the law of multiplication of surds
(
)² = (
(2) (
)× (
) =
Also applying the the law of multiplication of surd
(
)×(
) = (
) ( This is an irational answer)
∴ (
)×(
) = 
(3) 2(
)×3(
)
Also applying the law of multiplication of surds i.e Multiply surds to surds and whole number to whole number
= 2×3×(
