The sale price was 30% off the original price, which means it was on sale for 70% of the original cost ( 100% - 30% = 70%)
To find the original cost, divide the sale price by the percent of the original cost:
21 / 0.70 = 30
The original price was $30
check:
30 x 0.3 = 9 ( amount of discount)
30 - 9 = 21 ( sale price)
The formula for finding the circumference of a circle is 2πr or <span>πd
So, there are 2 ways to find it.
1) Using the diameter, you would do </span><span>π x 14.
This will give you </span><span>43.9822971503
(round the number to however many dp it says to do :) )
2) Using the radius (half of the diameter), you could do 2</span>π x 7
which will also get you <span>43.9822971503</span>
