You can't calculate the volume here as such the height is not mentioned here and for calculating volume you need height,breadth and length.

The area is 108cm2

Volume = pi*r2*h = 40715.04 cubic cm

SA = 904.78 cm2

Yes, the volume triples. When you have a height of 18, the volume will equal 864. (Volume of a pyramid is the area of the base x the height x 1/3)18*3=54. When you plug this in to the above listed formula, the volume will be 2592. Divide that by three and you get 864.

The area of a parallelogram with base 18cm and perpendicular height 18cm is 324 cm2

radius = 18/2 = 9 cm

12 + 24 + 18 = 54cm (Or 0.54 metres)

1,017.9 cm2

Using 3.14 as Pi the area of circle is: 1017.36

19.5cm, the value halfway between the two middle values.
