Question

the volume of a sphere is found using the formula V=4/3(3.14)r^3. The area of a circle is found using the formula A=3.14r^2. What is the ratio of the volume to the area?

Answer 1

Ratio = (4/3)R:1

Explanation:

The volume of a sphere with radius R = 4/3πR³

While the Area of a circle with radius R = πR²

The ratio of the volume to the area is the gotten by dividing the area from the volume.

So the ratio= ((4/3)πR³/πR²)

Ratio = (4/3)R:1

Answer 2

The volume of a sphere:
V = 4/3 π r³
The area of a circle:
A = π r²
Ratio = V / A = 4/3 π r³ : π r² ) = 4 r / 3
