Answer: ≈4.09π in. ≈12.85 in.

There are two hemispheres in there with radius 3 cm, so we can consider it as a whole one. and the other shape in between is Cylinder with radius 3 cm and height 4 cm.
Volume of whole ahape = volume of Cylinder + volume of sphere ~
<u>Volume</u> <u>of</u> <u>sphere</u> :




<u>Volume</u> <u>of</u> <u>Cylinder</u> :




<u>Volume</u> <u>of</u> <u>whole</u> <u>shape</u> :


Step-by-step explanation:
Since, diagonal of a parallelogram bisects it in two triangles of same area.
Hence, area of parallelogram ABCD will be twice the area of triangle ABD.

If you would like to calculate g * 5 - h * 3 for g = 2 and h = 7, you can do this using the following step:
g = 2
h = 7
g * 5 - h * 3 = 2 * 5 - 7 * 3 = 10 - 21 = - 11
The correct result would be - 11.
