Pls hurry my grade is bad rn

The perimeter of the circle is 138.23008

Step-by-step explanation:

The equation to do this is 2πR, the R standing for radius.

The radius of this circle is 22.

For future reference, the radius of any circle is HALF of any line going all the way through the circle, or, like the line below, the whole line.

Good luck with your class, I hope things get better! If ya need anymore help, feel free to let me know.  

the car was traveling 40 mph before it started skidding. ( 2 points ) 17. was the driver were her brakes working at 75% efficiency or better? ( 2 points ) yes 29.

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
