a cylindrical container that contains three balls that are 2.7 inches in diameter is standing on its base and passes through an x-ray scanner in an airport. what outline will appear on the x-ray screen, and with what dimensions?
a: a rectangle that is 2.7 in x 8.1 in
b: a rectangle that is 5.4 in x 8.1 in
c: a circle with a diameter of 5.4 in
d: a circle with a diameter of 2.7 in

Option A: A rectangle that is 2.7 in x 8.1 in

Step-by-step explanation:

we know that

The perpendicular cross section of a cylinder is a rectangle

The base of the rectangle is equal top the diameter of the circular base of cylinder and the height of the rectangle is equal to the height of the cylinder

therefore

The outline that will appear on the x-ray screen is

A rectangle that is 2.7 in (diameter of the base) x 8.1 in (height of the cylinder)

I believe the answer should be D - A circle with a diameter of 2.7

Step-by-step explanation:

This is because a diameter is a straight line passing from one part of a circle to another and we can tell that the image is a cylinder.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
