The formula for finding the surface area of a cone using the slant height is:
SA = pi * r * l + pi * r^2
where SA stands for surface area, r stands for radius, and l stands for slant height
Therefore, we can simply plug in all of the given values into the formula to get our answer.
The equation we would solve would be:
SA = 3.14*4*5+3.14*4^2
This gives us 113.04
The answer that is closest to this would be 113
Therefore, the answer is 113
Hope this helped!!C:D
Answer:
There are 10 possible ways the student can schedule the three classes
Step-by-step explanation:
The college student is choosing 3 classes to take during the first, second, and third semester from 5 electives.
Therefore, the student is choosing 3 items from a total of 5 and the order is not of key concern here. This is thus a combination problem;
5C3 = 10
read as 5 choose 3
The above mathematical operation can be performed using any modern calculator.
Step-by-step explanation:
well, it is supposed to be -3.
but you are right. something is wrong or missing here.
5x + 3 = 4x
x + 3 = 0
x = -3
maybe a "+ 1" is missing on the right side ?
5x + 3 = 4x + 1
gives us
x = -2
X = 13, Y = 10
I'm a bit tired right now, so I'm not going to explain my work, but hopefully this still helps.
Good luck with your schoolwork/homework!
