What is the equation of a circle with a center at (1,1) and a radius of 5 ?

The equation of a circle:

where

(h, k) - the coordinates of a center

r - the radius

We have

(1, 1) → h = 1 and k = 1

r = 5

Substitute:

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

the correct answer is 828.07
