Answer:
6165.0589
Step-by-step explanation:
Since $14 is the price after a 30% discount then $14 is 70% of the original price.
$14/70=x/100 (100% would be the original price)
1400=70x or 1400/70 = $20!
You can double check the work by taking 30% off the $20 (10% would be $2, 30% would then be $6) 20-6=14!
You would need to find the circumstance which the formula is pi*D. with D being the diameter. you would multiply 14 by 3.14 and get 43.96. Therefore the circumstance would be 43.96. hope this helped
