A factory wants to fill a conical storage tank with sand. The tank has a height of 19.5 meters and a diameter of 30.7 meters NOTE: Figure not drawn to scale
Calculate the volume of the storage tank to the nearest hundredth.

9514 1404 393

  4,811.49 m³

Step-by-step explanation:

The volume of a cone is computed using the formula ...

  V = (1/3)πr²h

Using the given numbers, we find the volume to be ...

  V = (1/3)π(15.35 m)²(19.5 m) = 1531.54625π m³ ≈ 4,811.49 m³

Additional comment

If you inappropriately use 3.14 for π, you get a volume of 4809.06 m³. That 3-digit value is inappropriate because a value accurate to 6 significant figures or more is needed to support an answer accurate to 6 significant figures.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
