Step-by-step explanation:
Volume of a cylinder : πr^2*height.
Volume : 150cm^3
height : 7.2m
π =3.14
150 = 3.14*r*r*7.2
150=22.608*r*r
r^2= 150/22.608
=150/23cm^2
r=√6.5
r=2.569cm
r=2.6cm
Answer:
the circumference is 31.4

Hello!
Circumference of a Circle
C=πd
or
C=2πr
Plug in the values
C=14π
C≈44 cm
C=2π×3.5
C≈22 cm
Hope everything is clear.
Let me know if you have any questions!
