Answer:

652.07 cm³  (2 decimal places)

Step-by-step explanation:

Volume of cylinder V = π · r² · h where r is the radius and h = height

r = diameter/2 = 10/2 = 5 cm

To find h note that the diagonal internal length of 13cm, the diameter of the base of the cylinder of 10 cm and the height h of the cylinder form a right triangle with 13 cm as the hypotenuse, diameter d as one leg and h as the other length

By the Pythagorean theorem

d² + h² = 13²

10² + h² = 13²

100 + h² = 169

h² = 169 - 100 = 69

h = √69 ≈ 8.3 cm

Using π = 3.14 and plugging in r and h values into the volume formula we get

V = 3.14 x 5² x 8.3

= 652.0699.. cm³

= 652.07 cm³  (2 decimal places)
