The lateral area of a cylinder is given by:
Area=πrl+2πr^2
radius,r=12 mm
length,l=5*12=60mm
therefore the lateral area will be:
Area=π*12*60
Area=2,261.95 mm^2
The area of the bases will be:
A=2*π*12^2=904.78 mm^s
The lateral area will be:
2,261.95+904.78
=3,166.73
=3167 mm^2
Answer:
5(9b + 8)
Step-by-step explanation:
Rewrite 45 as 5 * 9
Rewrite 40 as 5 * 8
= 5 * 9b + 5 * 8
Factor out common term 5
=5 (9b + 8)
1/3 belongs to the rational set and to the real set.
<h3>
To which sets does the number below belong?</h3>
Here we have the number 1/3.
First, remember that we define rational numbers as these numbers that can be written as a quotient between two integers.
Here 1 is an integer and 3 is an integer, then 1/3 is a rational number.
Also, the combination between the rational set and the irrational set is the set of the real numbers, then 1/3 is also a real number.
Then, concluding:
1/3 belongs to the rational set and to the real set.
