Answer:
A cylinder with a volume of 27 cubic inches and a height of 3 inches
Step-by-step explanation:
- Volume of a cylinder =
r²h
(where r is the radius and h is the height)
Volume = 27
Height = 3
⇒ 27 = 3
r²
⇒ 9 = r²
⇒ r = √9 = 3
So height = radius
I think that is the answer to your question if not I'll figure it out

The hardest part is finding the length of the curve at the top. To find arc length, multiply the circumference by the arc angle divided by full angle (360°) in a circle. Or:
x, the arc angle in a semicircle, is 180°.
r, the radius is 7/2 = 3.5.
Now just plug the numbers in and solve for arc length, s.
s = 2π(3.5)(1/2) ≈ 11.00
Now just add up all the sides. 11cm + 10cm + 10cm + 7cm = 38 cm.
