Answer: Circumference of Earth= 25120 miles
Step-by-step explanation:
Given: The circumference of a circle can be found using the formula
, where d= diameter of the circle.
Earth's diameter = 8000 miles (approx)
The circumference of circle =
[substitute values in formula]
The circumference of circle = 25120 miles (approx)
Hence, the circumference of Earth= 25120 miles (approx)
Cross multiply or just multiply both sides by 24
24x/6=36
4x=36
divide both sides by 4
x=9
X - 0.40x = 60
0.60x = 60
x = 60 / 0.60
x = 100 <== ur number
I don’t know if that’s what you wanted but I hope I helped ;D (sorry for my bad english)
