Which is an equation of a circle with center (-10, 6) and radius 8?

A: (x + 10)2 + (y - 6)2 = 8

B: (x + 10)2 + (y - 6)2 = 64

C: (x - 6)2 + (y + 10)2 = 64

D: (x - 10)2 + (y + 6)2 = 8

The answer to your question is letter B.

Step-by-step explanation:

Data

Center = (-10, 6)

radius = 8

Process

1.- To find the answer to your question just substitute the values in the standard form of the circle.

Equation

                    (x - h)² + (y - k)² = r²

h = -10

k = 6

r = 8

Substitution

                   (x + 10)² + (y - 6)² = 8²

Simplification

                   (x + 10)² + (y - 6)² = 64

600,000,000,000, or 6e14

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
