Question

Please help me this is urgent.!

Answer 1

V = 314 mm³

Explanation:

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

Here diameter = 10, hence r = 10 ÷ 2 = 5 and h = 4, thus

V = π × 5² × 4

= 3.14 × 25 × 4 = 3.14 × 100 = 314 mm³

Answer 2

V= 3.14• 5^2•4
V= 3.14 •25•4
V= 78.5•4
V=314

Sorry I couldn’t give a more detailed explanation but here is the original equation for volume of a cylinder:

V=πr2h
