so, perimeter = sum of all sides
= 4 + 8 + 8
<h3> = 20cm</h3><h2>-------------------------------------</h2><h2>FOLLOW ME</h2>
Answer:ok
Step-by-step explanation:
In order to solve this using V= B(h) (The B is area of the base) you need a radius it doesn't give us that but it does give us the circumference.
C= 3.14(2r)
25.12=2r divide each by 2
12.56=r
now use this in the volume formula:
V= 12.56^2(3.14)(66)
V=32,692.86 cubic inches
