The center of a circle is located at (6, −1) . the radius of the circle is 4.
what is the equation of the circle in general form?
x2+y2−12x+2y+21=0
x2+y2−12x+2y+33=0
x2+y2+12x−2y+21=0
x2+y2+12x−2y+33=0

ANSWER

Option A

EXPLANATION

When a circle has it's center at (h,k) and and radius r units, then its equation in standard form is

The given circle has its center at (6,-1) and its radius is r=4 units.

We plug in these values to get

We now expand to obtain

This is the equation in general form of the circle.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
