Question

A cylindrical metal pipe has a diameter of 8.4 millimeters and

Answer 1

Volume of a cylinder = pi x radius^2 x height of cylinder and diameter/2 is the radius so...

3.14 x (8.4/2) ^ 2 x 10 = 553.9

Since there is a hole that means you have to find the volume of the hole and subtract that from the volume of the whole pipe (553.9)

3.14 x (6/2) ^2 x 10 = 282.6

553.9 - 282.6 = 271.3

Answer 2

Answer:

271.3mm

Step-by-step explanation:

d=8.4

h=10

r=4.2

A=(3.14(4.2^2)) 10

A=554.176944093

d=6

h=10

r=3

A=(3.14(3^2)) 10

A=282.743338823

Now you're going to want to subtract the second area from the first area to get the leftover amount.

554.176944093 - 282.743338823 =271.433661177

~271.3mm
