Answer:
43
Step-by-step explanation:

Answer:
14.2 Units
Step-by-step explanation:
The second shape is given to confuse you and is not actually necessary.
To work out the perimeter of an irregular shape you simply add up the lengths of each side. The shape you have here is an irregular quadrilateral as it has four corners and no recognisable/coarrale organisation.

I hope this helps :)
Answer:
635.2 cm^3.
Step-by-step explanation:
Volume of the cylinder = π r^2 h
= 3.14 * 4^2 * 5 = 251.2
Volume of the prism = 4 *8 * 12
= 384
Total volume = 384 + 251.2
Answer:
Step-by-step explanation:
Volume v = 1/3(l×b)h
l = 29m, b = 24m, h = 20m
V = ⅓ ×(29×24)20
V = 29 × 8 × 20
V = 4640m³
