PLEASE HELP! (c) Complete the table to represent the relationship between volume and surface area of a spherical structure surro
Anuta_ua [19.1K]

Answer/Explanation:

Recall:

Volume of a sphere = ⁴/3πr³

Surface Area = 4πr²

✔️For radius (r) = 1 mm:

Volume = ⁴/3 × π × 1³ = 4.19 mm³

Surface Area = 4 × π × 1² = 12.57 mm²

Ratio of volume to surface area = 4.19 : 12.57 = 1:3

✔️For radius (r) = 3 mm:

Volume = ⁴/3 × π × 3³ = 113.1 mm³

Surface Area = 4 × π × 3² = 113.1 mm²

Ratio of volume to surface area = 113.1 : 113.1 = 1:1

Explanation:Following are the techniques or methods or approaches we can say that were used by the scientists to determine the geologic age:

1. Relative age dating

2. Absolute age dating.

3. Radiation measurement.

4. Stratigraphic superposition.

5. The fossil record.

The scientists used the method of relative dating to divide Earth's past in different chunks of time when alike organisms were on Earth. After that, to discover the actual number of years ago that events occurred, the scientists used the method of absolute dating.
