Answer:

The approximate volume of the tank is V=16,747\ ft^{3}

Step-by-step explanation:

we know that

The volume of a hemisphere (water storage tank) is equal to

V=\frac{4}{6}\pi r^{3}

we have

r=20\ ft

assume

\pi =3.14

substitute

V=\frac{4}{6}(3.14)(20)^{3}

V=16,747\ ft^{3}

For each parallelogram find the length of the base or height the first parallelogram has the area of 60 meters square the base i
Lynna [10]

Answer:

  5 m

Step-by-step explanation:

You know the area of a parallelogram is the product of its base length and height:

  area = base × height

Fill in the given values, and solve for height:

  60 m² = (12 m) × height

  (60 m²)/(12 m) = height = (60/12) m

  height = 5 m

The height is 5 meters.
