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)
Answer:Therefore, the relationship will be of the form, y = mx + b, or in this case, d = (max distance / max time)t + 0.
Step-by-step explanation:
Answer:
6d+49.8
If looking for d=8.316 but 6 is repeated
Step-by-step explanation:
Answer:
Read below
Step-by-step explanation:
a) 
b) 
(The reason both numerator and denominator can both be negative is because the negative cancel each other out and still simplify to 
)
the picture in the attached figure
we know that
if ABC is an isosceles triangle
then
AB=BC
angle A=angle C=45 degrees
and
triangle ABD and triangle BDC also are isosceles triangles
AD=BD=x
DC=BD=x
the hypotenuse AC is equal to
To find the length AB applying the Pythagorean Theorem
remember that AB=BC
therefore
the answer is
the length of one leg of the large right triangle in terms of x is equal to
