10 because 7 x 3 = 21 and 7 + 3 = 10 so your answer is 10

The only factors of 21 are: 1 and 21 or 3 and 7.

Since the two number mentioned are single digits, the numbers being used must be 3 and 7.

To get the sum, just add them together!
3 + 7 = 10

The answer to your problem is 10.

Hope this helps!!

Answer:

Volume of Pipe is 226 ft³.

Step-by-step explanation:

Given:

Cylindrical Shape Pipe having

Height = 18 ft

Diameter = 4 ft

∴ $Radius =\frac{Diameter}{2}=\frac{4}{2}=2\ ft$

To Find:

Volume of Pipe = ?

Solution:

Formula for Volume of Cylinder is given by

$\textrm{Volume of Cylinder}=\pi (Radius)^{2} \times Height$

Substituting the given values we get

$\textrm{Volume of Pipe}=3.14\times 2^{2} \times 18\\\\\textrm{Volume of Pipe}=226.08\\\\\therefore \textrm{Volume of Pipe}=226\ ft^{3}$

Volume of Pipe is 226 ft³.
