Answer:
The estimate value of the world's radius is 6384 kilometers ⇒ A
Step-by-step explanation:
The formula of the circumference of a circle is C = 2πr, where r is the radius of the circle
∵ The circumference of the world is 24,901 miles
∵ C = 2πr
- Substitute C by 24,901 to find r
∴ 24,901 = 2πr
- Divide both sides by 2π
∴ = r
∴ The radius is 3965.127389 miles
Change the mile to kilometer
∵ 1 mile = 1.60934 kilometers
- Multiply the value of the radius by 1.60934
∴ r = 3965.127389 × 1.60934
∴ r = 6381.238111 kilometers
- Round it to the nearest kilometers
∴ r = 6381 kilometers
The world's radius is 6381 kilometers
The nearest choice for this value is A
The estimate value of the world's radius is 6384 kilometers
