Answer:
Step-by-step explanation:
Total Surface Area of Cylinder =
Note: Do not get tricked by the 24cm (taking 24cm as the radius), that is the diameter.
To find r, radius =
=
= 12cm
Now we know r = 12cm, h = 18cm
Now we substitute r and h into the formula to find the total surface area.
Total Surface Area of Cylinder =
Answer:
-1/4
Step-by-step explanation:
(Y2-Y1)/(X2-X1)
-7-(-3)/7-(-9)=-4/16=-1/4
Answer 17 black and 18 blue
Step-by-step explanation:
A bead cant be split in half so one has to have more
Hm. This is an interesting problem.
Let's see if we can express each of these numbers in terms of x and make an algebra equation to help us solve.
Consecutive even numbers increase by 2.
Let's allow x to equal our first number.
Let's allow x + 2 to equal our 2nd number.
Let's allow x + 4 to equal our 3rd number.
When we add those together, their sum need to equal 50 more than the largest integer (our x + 4)
Let's set it up!
x + (x +2) + (x + 4) = (x + 4) + 50
Simplify!
3x + 6 = x + 54
Let's reorganize the left and right sides.
3x - x = 54 - 6
2x = 48
x = 24 (our 1st even number)
Now, let's check our answer!
24 + 26 + 28 = 78
78 - 50 = 28 Our highest integer.
The sum of consecutive integers 24, 26, 28 is 50 more than the highest integer.
