Answer:
180
Step-by-step explanation:
Volume = base * height(depth)
V=1.2*1.35=1.62 m³
1 m³=1000 liter
1.62*1000=1620 liter
1620/9=180 ( 9 liter bucket)
Answer:
37.7 mi²/h
Step-by-step explanation:
The area formula is ...
A = πr²
Differentiating with respect to time gives ...
dA/dt = 2πr·dr/dt
Filling in the given values, we have ...
dA/dt = 2π(3 mi)(2 mi/h) = 12π mi²/h
The area is increasing at the rate of about 37.7 mi² per hour.
Answer:
25.1349955242 m²
Explanation:
C = 2√πA
This means that the circumference is 2 multiplied by the square root of pi. multiplied by the area.
Pi. - 3.14
Area - 50.3
√πA - 12.5674977621
2 · 12.5674977621 = 25.1349955242
Circumference - 25.1349955242
