Hello!

To find the circumference of a circle you do 2 \pi r where r is the radius of the circle

So we do 2\pi 72

Then we substitute pi for 3.14

2 * 3.14 * 72 = 452.16 yds

Then we multiply this by 5 since he runs 5 laps

Which gives us the answer of 2260.8 yds

Hope this helps!

What is the simplest form of the expression (–12.7y – 3.1x) + 5.9y – (4.2y + x)?
Doss [256]

Answer:

<h2>-11y - 4.1x</h2>

Step-by-step explanation:

(-12.7y-3.1x)+5.9y-(4.2y+x)\\\\=-12.7y-3.1x+5.9y-4.2y-x\qquad\text{combine like terms}\\\\=(-12.7y+5.9y-4.2y)+(-3.1x-x)\\\\=-11y-4.1x

The points J (-13,10) and K(-1,-6) are endpoints of a diameter of circle G. What is the equation of circle G?
In-s [12.5K]
The correct answer is D

The equation of a circle is (x-h)^2 + (y-k)^2 = r^2

to find (h,k), you find the middle of the circle, in this scenario you do so by finding the middle of the diameter, a line that goes through the center of the circle.

To find the X value of the midpoint, add both x values together and divide by 2 and repeat for y

-13 + -1 = -14
-14/2 =-7

10+ -6 = 4
4/2 = 2

therefore (h,k) = ( -7, 2 )

Next plug these values in the equation of a circle

(x-h)^2 + (y-k)^2 = r^2

becomes

(x- (-7)) ^2 + (y-(2)) ^2 = r^2

to find r, use the distance formula to find the length of the diameter, 20, and divide by 2


plug 10 in for r and you get 100

(x+7)^2 + (y-2)^2 = 100

sorry for the late response
