The total surface area of Earth is about 1.97 × 10^8 square miles. The surface area of land on Earth is about 5.73 × 10^7 square miles.

Find the ratio of surface area of land to that of the entire planet.

Thank you so much!

To find the ratio of the surface area of land to the total surface area of the Earth, divide the surface area of land by the total surface area of the Earth.

Surface area of land: 5.73 × 10^7 square miles
Total surface area of Earth: 1.97 × 10^8 square miles

The ratio is:

(5.73 × 10^7) / (1.97 × 10^8)

To simplify the ratio, divide both the numerator and denominator by 10^7:

(5.73 / 1.97) × (10^7 / 10^8)

= 2.908 × 10^-1

Therefore, the ratio of surface area of land to the total surface area of the Earth is approximately 0.2908 to 1, or 29.08%.

To find the ratio of the surface area of land to that of the entire planet, we need to divide the surface area of land by the total surface area of Earth.

The surface area of land is given as 5.73 × 10^7 square miles, and the total surface area of Earth is given as 1.97 × 10^8 square miles.

So, the ratio can be calculated as:

Ratio = Surface area of land / Total surface area of Earth

Ratio = (5.73 × 10^7 square miles) / (1.97 × 10^8 square miles)

To simplify, we can divide the numerator and denominator by 10^7:

Ratio = (5.73 / 1.97) × (10^7 / 10^8) square miles

Ratio = 2.908 × 10^(-1)

Therefore, the ratio of the surface area of land to the entire planet is approximately 0.2908.

divide the surface area of land by earth

5.73/1.97 10^7/10^8

2.91 x 10^-1 = .291
