The equation to find the circumference of a circle is ...
c = π × d
All we need to do to find circumference is to <em><u>multiply</u></em> the diameter (16km) by pi (π)
c = π × 16
c = 50.27
Answer:
The actual area of land is 80 mi² .
Step-by-step explanation:
Given that we have to find the actual area so first we have to square the ratio(scale factor) :
1 in : 5 mi
(1 in)² : (5 mi)²
1 in² : 25 mi²
Next, the actual area will be :
1 in² = 25 mi²
(1 × 3.2) in² = (25 × 3.2) mi²
3.2 in² = 80 mi²
First we need to convert cm to mm
45 cm = 450 mm
Now our ratio looks like this
60/450
We can divide both by 30 and once we do that our ratio will look like this:
2/15
That means the answer is B
