Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h. k) are the coordinates of the centre and r is the radius
here (h, k ) = (- 6.2, 5.8 ) and r =
, hence
(x + 6.2)² + (y - 5.8)² = (
)²
(x + 6.2)² + (y - 5.8)² =

Multiply both sides by 3:

Recall that 21/5=4.2 to claim the correct answer.
This is a question on Present Value of Annuity and we seek the periodic withdrawal.

where:
FVA = Future value of annuity
PMT = Periodic Withdrawal
i = interest/discount rate
n = no of years
m = no of compundings per interest period

PMT = $22.01
