1570 m3

Answer 1

@RadEn help plz

Answer 2

use this formula :
Volume = pi * r^2 * h
with r = radius and h = height

Answer 3

39.26990817

Answer 4

ok, known that h = 2
and diameter = 5 * 2 = 10
therefore its radius = d/2 = 10/2 = 5 meters

now, evaluate this
V = pi * r^2 * h
V = 3.14 * 5^2 * 2
V = 3.14 * 25 * 2
V = ... ?
