Answer:
160 square feet
Step-by-step explanation:
you would do 2*8*10 to get 160 which would be your square surface area
Ok, so here, we need to use the slope formula which is:
(y2 - y1)/(x2-x1)
y2 = 9
y1 = 5
x2 = x
x1 = 10
So:
(9-5)/(x-10) = -2
Now, we just solve for x,
9-5 = -2(x-10)
4 = -2x+20
2x = 16
x = 8
Answer:
5 students
Step-by-step explanation:
9 students studied for more than 3 and 4 students studied less .
9-4=5
Step-by-step explanation:
The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :

or

We also know that, surface area = perimeter×height
So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.
The answer would be <em>29.5562243957</em>.
