Answer:
221 cubic metre.
Step-by-step explanation:
Volume of water in tank (v) = π × {3}^{2} × 6
= 54π cubic metre
Volume of tank (v') = π × {5}^{2} × 11
= 275π cubic metre
More Water that can be fit in the tank = v' - v
=275π - 54π
= 221π cubic metre.

Answer:
cosB = 2√6 / 7
Step-by-step explanation:
use the pythagorean theorem to find the missing side
a² + b² = c²
a² + 5² = 7²
a² + 25 = 49
a² = 24
a = √24
a = 2√6
--------------------------
cosB = adj/hyp
cosB = 2√6 / 7
The answer is probably C or D
330/3= 110
550/110=5

Answer:
The three period moving average forecast for week 6 is 24.
