let h= 3, k=-2

radius (r) = 11 ,then

(x-h)^2 + ( y-k)^2 = r^2

(x-3)^2 + ( y+2)^2 = 11^2

x^2 -6x +9 + y^2 +4y +4 = 121

x^2 + y^2 - 6x +4y -108 = 0 is the required eq

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

The coins are in the ratio 2:5:7 respectively. If he has a R90 in R2 coins. If x represent the total coins, hence:

(5/14) * x = 90

x = 252

Number of R5 coins = (2/14) * 252 = 36

Number of R1 coins = (7/14) * 252 = 126

Andrew has saved 36 number of R5 coins, 90 number of R2 coins and 126 number of R1 coins,
