A. if u unfold a cylinder, it is a circle, a rectangle, and a circle.
Find the area of those
to find the area of the circle, you need the radius.:
14/2= 7
To find the area of a circle, it is 3.14*r^2
=3.14*49
= 1538.6
Now you have to multiply it by 2 because there are two circles: 3077.2
Now find the area of the rectangle:
To find the area, you have to have the height (20cm) and the width of the rectangle/the circumference of the circle.
To find the circumference: 2*3.14*r(7)
= 2*3.14*7
=43.96
Now that you have that, you can find the area
43.96*20
=879.2
Now you add both products together
879.2+ 3077.2
=3956.4cm^2
B. divide 3956.4 by 3
=$1318.8
C. volume of cylinder: 3.14*r(7)^2h(20)
calculate that you get
3077.2
Hope that helps, and please notify me if I am wrong.
Rational numbers are sometimes natural numbers.

Answer:
the answer is i
Step-by-step explanation:
logic
If you try to solve for x it is not able to be solved because the variable must be located in between the inequality signs, but if i simplified your problem then it would be: x is greater than or equal to -2.
I really hoped this helped. Good luck.
