Answer:
22,000 miles
Step-by-step explanation:
Circumference of a circle: 2πr (r is the radius)
Substitute the length of the radius given, which is 3500. Also, substitute the approximate value of π, which is 3.14.
Circumference = 2 * 3.14 * 3500
Circumference = 21980
This rounds to about 22,000, so the answer is 22,000 miles.
I hope this helps! Feel free to ask any questions!
Answer:
A, C, D
Step-by-step explanation:
Remember: Exponents are simply repeated multiplication.
The exponent determines how many times to multiply the base number by itself.
Option 'A' and 'C' apply.
Option D applies because:
The population ten years ago was 6,000.
Because the population doubled you divide 12,000 by 2
12,000 / 2 = 6,000
Compare each place value. It's kind of hard to explain without examples...
4(4x+10)=360
16x+40=360
-40 -40
16x=320
÷16 <span> ÷16

x=20
