You need to show us the circle in order to let us answer the question.
4×10^6 you subract the exponents when dividing and divide the number multiplying the 10
The circumference of a circle is pi times D. So, 94.2/pi = 29.98 or about 30 in
I’m pretty sure it’s y if not I’m sorry
Answer:
3.1567 * 10^-4 miles
Step-by-step explanation:
1 ft = 1.894 * 10^-4 miles , so
1 inch = 1.894 * 10^-4 / 12 miles
= 0.15783 * 10^-4
= 1.5783* 10^-5 miles ( in scientific form).
Multiplying this by 20 we get
31.567 * 10^-5
= 3.1567 * 10^-4 miles.
