Answer:
V = 4/3 pi or approximately 4.187 ft^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
The radius is 1 ft
V = 4/3 pi (1)^3
V = 4/3 pi
We can approximate pi by 3.14
V = 4/3 (3.14)
V = 4.186666666 ft^3
Answer:
1857 miles.
Step-by-step explanation:
We have been given that the scale on a map is 1 cm:30 mi. The distance on the map between San Francisco, CA, and Chicago, IL, is 61.9 cm. We are asked to find the actual distance between San Francisco and Chicago.
We will use proportions to solve our given problem.

Upon substituting map distance between San Francisco and Chicago, we will get:




Therefore, the actual distance between San Francisco and Chicago is 1857 miles.
