$3.20
2.99 • 7% = 0.2093
2.99 + 0.2093 = 3.20
If using the radius, you would multiply the radius by 2*pi, to calculate the circumference, which should be the same as the answer i got.
It would be: 420 + (420 * 17.5%)
= 420 + (420 * 0.175) [ 17.5% = 0.175 ]
= 420 + 73.5
= 493.5
In short, Your Answer would be <span>£493.5
