A circle is entered on the point (-1,5) and contains the point (7,11). What is the area of this circle?

100π units square

Step-by-step explanation:

The circle is centered on the point (-1,5) and contains the point (7,11).

We can find the radius, using the distance formula,

We substitute the points to get:

This implies that:

The area of a circle is given by:

Plug in the radius into the formula to get:

The area is 100π square units or 314 square units

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
