# Cylinder volume with height h = 5000000000000000000 and the radius of the base r = 999999999999 equal 1.5707499999969E+43

a: Cylinder volume with height h = 5000000000000000000 and the radius of the base r = 999999999999 equal 1.5707499999969E+43

A cylinder is a geometric body closed between two parallel bases that are circles.

Cylinder volume formula:
where h is the height of the cylinder,r is the radius of the base

Solution:

V = π·r^{2} · h

= π·999999999999^{2} · 5000000000000000000

= π·9.99999999998E+23 · 5000000000000000000

= 4.99999999999E+42·π

=

1.5707499999969E+43
