Ijust can’t understand the question.

Hi,

It is very easy question. (but difficult to explain in a foreign language).

First of all you are suppose to find out the area of a circle, which is a base of a cylinder.

You have at your disposal a sheet of paper 4 x 6 cm.

So there are two possibilities of rolling up this piece of paper: you can roll it along the longest edge, or along the shortest one.

But in the task you are told to roll it along the shortest edge.

Hence you know that the circumference of a circle is 4 cm.

now you have to find the ray of the circle.

it is easy if you know the circumference.

circumference = 2 π * r

r = circumference / 2 π

r = 4 / 2 (3,1415)

r = 4 / 6,283

r = 0,6366

Now, if you know the ray of the circle, you can find the area.

Area = π*r^2

A = 3,1415 * (0,6366)^2

A = 3,1415 * 0,4053

A = 1.2732

i.e. the first option in your task.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

b if for most of the graph

d if y intercept
