Answer:
36 but im not sure
Step-by-step explanation:
ok so you would have to do A=lwh which is A=2x3x6+36
We know that
volume of a right circular cylinder=pi*r²*h
where
r ----> is the radius
h---> is the height
in this problem
r=6 cm
h=?
Volume=550 cm³
so
V=pi*r²*h------> h=V/[pi*r²]----> h=550/[3.14*6²]----> h=4.87 cm
<span>Round to the nearest tenth
</span>h=4.9 cm
the answer is
4.9 cm
