Answer:
I': (-1, 4)
J': (3, 5)
K': (3, 2)
Step-by-step explanation:
to find the new 'x' values, add 2 to original 'x' values
to find the new 'y' values, add 6 to original 'y' values
28/14 divided by 7/7 = 4/2 divided by 2/2 = 2/1 = 2
It would take them 12 minutes to finish 1 mile.
60 minutes/5 miles= 12 minutes
The total surface are of cylinder comprises of the lateral or curved surface area + the area of the flat surface on the top and bottom
The lateral surface area is calculated this way
curved area of the face × height
Here it is a circle and hence its circumference is 2πr
Hence the formula become
2πr × h = 2πrh
So 2πrh is the part that represents the curved area of the cylinder
(Additional info: The area of the faces is given by πr² for one side, since a cylinder has 2 faces
we have πr²+πr²=2πr²
Hence the total surface area is 2πrh +2πr²)
