volume of cylinder = area of base * depth of cylinder
area base = diameter ^ 2 multipilied to pi / 4 or
radius ^ 2 multiplied to pi
where pi = 3.1416
given:
diameter = 28 m
height or depth = 7 m
solution:
1.
volume of tank = (28^2 * pi/4) * 7 = 4310.27... cu.m.
2.
volume of tank = (28/2)^2 * pi * 7 = 4310.27...cu.m.

V = Ï r² h
V = Ï x 14² x 7 m³
V = 4310 m³ ( to nearest whole number)

the formula is pie R sqaure times height = volume of a cylinder
3.1415972.... .x 14^2 x 7 = your volume

you poor thing
THe equation for volume of a cylinder is 3.14X.5D squared
so this answer is 3.14X.5X7X.5X7X28 = 1077.02 meters cubed
