How the sales tax calculator works
Step 1: take the total price and divide it by one plus the tax rate.
Step 2: multiply the result from step one by the tax rate to get the dollars of tax.
Step 3: subtract the dollars of tax from step 2 from the total price.
Pre-Tax Price = TP – [(TP / (1 + r) x r]
TP = Total Price.

Step-by-step explanation:
The circumference of a circle = 2*pi * r
so 16 pi yards = 2 * pi * r
Divide both sides by 2
16 pi/2 = 2*pi * r /2
8*pi = pi * r
Divide both sides by pi
8 * pi / pi = pi * r / pi
r = 8
====================
Surface Area = 4 pi * r^2
r = 8
Surface Area = 4 * pi * 64
Surface Area = 256 * pi
