Answer:
You can solve this by having 2 different equations and setting both of them to 180 because they are supplemetnary anhles
Step-by-step explanation:
so for abc the equation= 180, then solve
then for the other angle cbd=180, then solve
Question 1
2+2x
2+2(7)
2+14
16 dollars
question 2
3+2h=p
Answer:118
Step-by-step explanation:
It has to equal 180 degrees in total so 48+14=62
180-62=118
So the answer is 118
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.
