radius of 3960 miles cause there 5280 feet find length in feet by circumference of earth use ~3.14
Convert r=3960 miles to feet by multiplying by 5280 ft/mile to get
r=20908800 ft.
Use
circumference = 2*π&r
to for the circumference.
To find the length in feet of the circumference of the Earth using a radius of 3960 miles, you can follow these steps:
Step 1: Convert the radius from miles to feet.
Since there are 5280 feet in a mile, you can convert the radius of 3960 miles to feet by multiplying it by 5280:
3960 miles * 5280 feet/mile = 20,908,800 feet
Step 2: Calculate the circumference using the formula C = 2 * π * r, where C is the circumference and r is the radius.
Using the approximate value of π as 3.14, substitute the radius (20,908,800 feet) into the formula:
C = 2 * 3.14 * 20,908,800 feet = 131,383,104 feet
Therefore, the length in feet of the circumference of the Earth, using a radius of 3960 miles, is approximately 131,383,104 feet.
