A spherical ball of wax with a radius of 8 inches is melted and poured into a container shaped like a rectangular prism with a 1
avanturin [10]

It is expected the height of the melted wax in this shape is 9.57 inches, this height would make the volume remain constant.

<h3>What is the volume of the spherical ball?</h3>

The volume of a sphere can be calculated using the formula V = 4/3 πr³. Let's use this formula to calculate the volume of the spherical ball of wax:

  • V = 4/3 π8³
  • V = 4/3 π 512
  • V= 4/3 x 3.1416 x 512
  • V =2144.66 cubic inches

<h3>What is the height of the new shape?</h3>

Considering the volume should be the same  (2144.66 cubic inches) and the volume of this shape can be calculated by multiplying the sides, this would be the equation:

  • 2144.66 = 14 x 16 x y ( unknown value)
  • y= 2144.66 / 14 x 16
  • y = 9.57

This means the height would be 9.57 inches.

a cylindrical bucket has a radius of 6 inches and a height of 18 inches. What is the minimum number of buckets of water needed t
ivanzaharov [21]

Answer:

Minimum 7 buckets of water is needed to completely fill spherical storage tank.

Step-by-step explanation:

We are given the following in the question:

Cylindrical bucket:

Radius, r = 6 inches

Height = 18 inches

Volume of bucket = Volume of cylinder

V = \pir^2 h \\V = 3.14\times (6)^2\times 18\\V =2034.72\text{ cubic inches}

Spherical storage tank:

Radius, r = 15 inches

Volume of tank = Volume of sphere =

V =\dfrac{4}{3}\pi r^3\\\\\V = \dfrac{4}{3}\times 3.14\times (15)^3\\\\V = 14130\text{ cubic inches}

Number of baskets required =

n = \dfrac{\text{Volume of tank}}{\text{Volume of bucket}}\\\\n =\dfrac{14130}{2034.72} = 6.94 \approx 7

Thus, minimum 7 buckets of water is needed to completely fill spherical storage tank.

I’d say it’s 2/1 since the rise is 2 and the run is 1 and slope I believe is rise/run. It’s been awhile So I’m not too sure this is the right answer. I hope it is.
