The approximate surface area of a sphere can be calculated using the formula:
Surface area = 4πr^2
Given that the radius of the sphere is 37.68 km, we can substitute this value into the formula:
Surface area = 4π(37.68)^2
Calculating this expression will give us:
Surface area ≈ 4π(1418.9824)
Surface area ≈ 5655.9296π
To approximate this value, we can use the approximation for π as 3.14:
Surface area ≈ 5655.9296 * 3.14
Surface area ≈ 17,766.758144 km^2
Rounded to one decimal place, the approximate surface area of the sphere is 17,766.8 km^2.
