1) False
2) True
3) True.
You can see for number one the angles are not the same, therefore they are not equal to eachother.
For two, because the line EC is running flat it is equal to 180. Because their is a little box on the other side of 1 & 2, we know that is equivalent to 90 degrees. Therefore the other side (1 &2) HAS to be 90, because the line in which they are on is 180, 90+ 90 = 180.
3, The same type of math for #2
Answer:27
Step-by-step explanation:
27-5=22
A- dot 1 . that’s the answer but it’s making me type 20 words.
We can find the area of the circles on top and bottom using pi*r^2
pi*1^2 = pi.. we have two circles so the total area is 2pi
For the remainder of the cylinder, let's flatten the tube into a rectangle. Imagine cutting a toilet paper roll and laying it flat. The height is given as 9, and the width is the circumference of the circle. C=2pi*r
So the area of the rectangle is 9*2pi*1 = 18pi
Add the 18pi and 2 pi for a total surface area of 20pi.
