The area of a sphere: A = 4.π.R²
A= 5541.77 → 5541.77 = 4.π.R²
R² = (5541.77)/(4.π)
R² = 441; → R =√441; R = 21 cm
Answer:
distance from Houston to Galveston in kilometers will be: 80km
Step-by-step explanation:
Given
The distance from Houston to Galveston is about 50 miles.
i.e.
Kilometers in 1 Mile = 1.6 km
