Formula of the circle
(x-a)² +(y-b)² = r²,
where r is a radius, (a,b) - coordinates of the center.
So,
x² + y² = 49
(x-0)² + (y-0)² = 49.
Center of this circle has coordinates (0,0).
x² + y² = 7²
r = 7

Answer: $14.0
Step-by-step explanation:
For us to calculate this question, we have to find 20% of $17.45 and then subtract the value gotten from $17.45. This will be:
= $17.45 - (20% × $17.45)
= $17.45 - (0.2 × $17.45)
= $17.45 - $3.49
= $13.96
= $14.0 to nearest cent
Since a fraction is a form of division, you do 21/2=10 and 1/2.
