The area of the surface of a sphere is described by the formula s=4(3.14)r^2. the earth has a radius of 3960 miles and dry land forms 29.2% of the earth’s surface. what is the area of the dry land on earth?

Step-by-step explanation:

Substitute the value of the radius of the Earth into the formula given in the problem, where r is the radius, to obtain the surface area of the Earth:

The problem says that the dry land forms 29.2% of the Earth’s surface, therefore, multiply the surface area by

Threfore, the area of dry land is the following:

i think it is 18
