Answer:
Yes
Step-by-step explanation:
A number that can be written as a ratio of two integers, of which denominator is non-zero, is called a rational number.
Therefore 2/3 is a rational number.
The surface area of a cylinder is given by:
A = 2 * pi * r * (r + h)
Where,
r: radio
h: height
Substituting values:
A = 2 * pi * 3 * (3 + 8)
Rewriting:
A = 2 * pi * 3 * (11)
A = 66pi square units
Answer:
A = 66pi square units
