A = pi(r^2)
1. Calculate radius:
r = d/2, so r = 18
2. Enter variable into equation
a = pi(r^2)
becomes a = 3.14(18^2)
3. Solve
a = 3.14(324)
a ~= 1018 in2
4. Convert to feet
1018/12 = 84 ft2
5. Multiply by unit rate
84(3.5) = $294
It will cost $294 to paint the sign.
The answer is 30.857142 = x
In order to solve this you need to do the original price - the sold price and figure the difference.
90-180= <span>£</span>18
therefore making it 20% of a profit sale.
There's no problem so we can't answer it
