Question

4. The Torrid Zone on Earth is the area between the Tropic of Cancer and the Tropic of

Capricom (lines of latitude close to the equator). The distance between these two
tropics is about 3250 miles. You can estimate the distance as the height of a cylindrical
belt around the earth at the equator.
Part A: If the radius of the Earth is 3960 miles, then estimate the amount of surface area of
the Torrid Zone (cylinder shape). Approximate to the nearest thousands place.

Answer 1

179,395,000 miles²

Explanation:

Radius = 3960 miles

Height = 3250 miles

Formula for area of cylinder =
`2\pi rh + 2\pi r^(2)`

2 ×
`\pi` × 3960 × 3250 + 2 ×
`\pi` × 3960²

= 179,394,993 miles²

Hope that answers the question, have a great day!
