Write an equation of the circle with center 6.-9) and radius 10!

The equation of the given circle is

Step-by-step explanation:

Step 1:

The equation of a circle with its center at (h, k) and a radius of r is given by

The h value is the x coordinate and the k value is the y coordinates, so (h, k) is (6, -9).

The radius is given as 10 so and

Step 2:

By substituting the values we know, we get

So the equation of the given circle is

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
