Write an equation of the circle with center (6, 2) and radius 4.

.

Step-by-step explanation:

is the equation for a circle with center (h,k) and radius r.

You are given center (6,2) and radius 4.

So we will replace h with 6 and k with 2 and r with 4.

This gives us:

Simplify:

.

For this case we have that by definition, the equation of a circle is given by:

Where:

It is the center of the circle

r: It is the radius of the circle

According to the data we have to:

Substituting:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
