Question

Find the difference in the volume and total area of a cylinder with both a radius and height of 1.

r = 1, h = 1

The number of sq units of the total area exceeds the number of cu. units in the volume by

3pi
2pi
pi

Answer 1

well do you have the formula?

Answer 2

No

Answer 3

What is the formula?

Answer 4

\[V = \pi*r^2*h\]

\[A = 2*\pi*r^2*+ 2*\pi*r*h\]

Answer 5

They said sq exceeds cm, so

\[Area-Volume\]

Answer 6

Total area of cylinder= curve surface area + area of circular end
= 2Πrh + 2Πr^2

Answer 7

Okay so for volume I would have V= 1^2 *1 * pi V=pi

And for area I would have A=2pi 1^2 + 2pi 1 * 1 A=2pi + 2pi A=4pi

4pi - pi= 3pi
Is this right?

Answer 8

Looks good to me

Answer 9

Okay. Thank you
