The approximate difference in the amount of wax will be 4.19 cubic inches. Then the correct option is A.
What is Geometry?
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Joel used candle molds, as shown, to make candles that were perfect cylinders and spheres:
A cylindrical mold is shown, the radius of the top circular section of the cylinder is labeled 2 inches and the height of the cylinder is labeled as 3 inches.
The volume of cylinder will be
V₁ = πr²h
V₁ = π x (2)² x 3
V₁ = 37.699 cubic inches
On the right side of this mold is a spherical mold. The radius of this spherical mold is labeled as 2 inches.
The volume of sphere will be
V₂ = (4/3)πr³
V₂ = (4/3)π x (2³)
V₂ = 33.510 cubic inches
Then the approximate difference in the amount of wax needed to make a candle from each of these molds will be
V₁ – V₂ = 37.699 – 33.510
V₁ – V₂ = 4.188
V₁ – V₂ ≈ 4.19 cubic inches
Then the correct option is A.
