Question

Estimate the surface area of the earth facing the sun in meters 2

Answer 1

Step-by-step explanation:

The area of the Earth that faces the Sun is 4 times pi times Earth's radius, or 4 X 3.1416 X 6371 square kilometers (km^2). That's 80 060 000 000 square meters.

Answer 2

Answer: $255.13$×$10^{12} \ m^{2}$

Step-by-step explanation:

• The area of earth which faces the sun will be half of the sphere.
• Surface area of a sphere=$4\pi r^{2}$
• ∴Surface area of hemisphere=$2\pi r^{2}$
• Radius of earth=6.371×$10^{6}m$
• Required area=$2*\frac{22}{7}*(6.371*10^{6} )^{2}$

                               =$255.13$×$10^{12} \ m^{2}$

• Hence,the required area is $255.13$×$10^{12} \ m^{2}$.
