Part A: If the radius of the Earth is 3960 miles, then estimate the amount of surface area of

Bond [772]

Answer:

Surface area of Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)

Step-by-step explanation:

Given:

Radius of the Earth = 3,960 miles

Find:

Surface area of Torrid Zone (cylinder shape) = ?

Computation:

We know that, distance between two tropics is 3,250 miles.

So, Height = 3,250 miles

$Surface\ area\ of\ Torrid\ Zone=2\pi rh\\\\Surface\ area\ of\ Torrid\ Zone=2\times \frac{22}{7}\times 3,960 \times 3,250\\\\Surface\ area\ of\ Torrid\ Zone=80,897,142.9$

Surface area of Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)
