Lets get started :)
The Volume formula of a Cylinder is
V = [tex] \pi [/tex]r²h
(r = radius, h = height)
The radius given is 8 and the height is 4, We can plug in the known values
V = [tex] \pi [/tex](8)²(4)
= [tex] \pi [/tex]256
= 256[tex] \pi [/tex] units³ (You can leave the answer in this form)
≈ 804.2 units³ (approximately)
Units³ because it is a volume (3D shape)
