Write an equation of the circle with center (-6, 2) and diameter 10.
marshall27 [118]

Solution:

We know that the formula to write the equation of a circle is (x – h)² + (y – k)² = r², where h is the x coordinate, k is the y-coordinate, r is the radius of circle, and the center of circle is (-6,2).

<u>Finding the radius of the circle.</u>

  • Diameter: 10 units
  • Radius: 10/2 units = 5 units

<u>Creating the equation:</u>

  • (x – h)² + (y – k)² = r²
  • => (x + 6)² + (y – 2)² = 5²

The equation is (x + 6)² + (y – 2)² = 5².

A dozen is 12 so you do 12x7=84

Then you do 103.32 divided by 84 which gives you 1.23

2. His error was doing 103.32 divided by 7 because he thought it was only 7 pairs but it’s 7 dozen.
