Answer:
72π (in terms of pi)
Step-by-step explanation:
V = π·r²·h
Plug in the values.
V = π·3²·8
Solve.
V = 72π
To leave an equation in terms of pi, just square, multiply, and leave pi at the end.
3² = 9·8 = 72
72π
If you need the answer fully simplified, it is 226.19 (rounded up).

Answer:
The circumference is approximately 125.66.
Step-by-step explanation:
The formula for circumference is 2 x 3.14(r). Radius (or r) in this case is equal to 20 since the diameter is two times the length of the radius. 40/2 = 20.
2 x 3.14(20) ≈ 125.66
It is most likely B because they sold 7 more today. C is probably the second most likely but either less daisy’s will need to be sold or 6 more lily’s will need to be sold so go with B
Answer:
The tank is 10cm high
Step-by-step explanation:
Given
-- length
-- width
--- water lever
Required
The height of the tank
Let y represents the remaining fraction before water is added.
So:
Make y the subject
Solve
Represent the volume of the tank with v
So:
Make v the subject
Substitute:
Represent the height of the tank with h;
So, the volume of the tank is:
Make h the subject
Substitute values for v, l and w
Convert 30L to cm^3
