how many is 12fl oz

so (1×12)/128=0.09375gallons per person

and you have 15 so if one consumes 0.09375 how many can consume 15

What is the equation of the circle with center (0, 1) and a radius of 10?
victus00 [196]

<u>Answer:  </u>

The equation of the circle with center (0, 1) and a radius of 10 is \bold{x^{2} + y^{2} - 2y-99 = 0}

<u>Solution: </u>

Equation of circle whose center (h, k) and radius r is given as,

(x-h)^{2} + (y-k)^{2} = r^{2} ---- eqn 1

From question, given that the circle has radius 10 and center (0, 1). We have to find the equation of the circle.

Hence we get, h = 0 ; k = 1; r = 10

By using eqn 1, the equation of circle whose center (0, 1) and radius 10 is given as

(x-0)^{2} + (y - 1)^{2} = 10^{2}

On Simplifying we get

x^{2} + (y-1)^{2} = 10^{2}

Expand (y-1)^{2} using the formula (a-b)^{2} = a^{2} - 2ab + b^{2}

x^{2} + y^{2} - 2y + 1 = 10^{2}

x^{2} + y^{2} - 2y + 1 = 100

x^{2} + y^{2} - 2y + 1-100 = 0

x^{2} + y^{2}- 2y- 99 = 0

Hence equation of the circle with center (0, 1) and a radius of 10 is  \bold{x^{2}+y^{2}-2 y-99=0}
