a plane intersects a cylinder parallel to the cylinder’s bases. what’s the area of the resulting cross section? use 3.14 for π. round your answer to the nearest tenth

The area of the resulting cross section is

Step-by-step explanation:

we know that

The resulting cross section is a circle congruent with the circle of the base of cylinder

therefore

The area is equal to

we have

-----> the radius is half the diameter

substitute the values

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
