What is the area of a cylindrical ring where the diameter of the cross section is 6.3 in and the center line has a length of 48

Nesterboy [21]

Answer:

The area of cylinder 949.536 in²

Step-by-step explanation:

Points to remember

Curved surface area of cylinder = 2πrh

Where r - radius of cylinder

h - Height of cylinder

To find the area of cylinder

Here r = diameter/2 = 6.3/2 = 3.15 in

h = 48 in

Area = 2πrh

= 2 * 3.14 * 3.15 * 48

= 949.536 in²

Therefore area of cylinder 949.536 in²
