The radius is 6
Complete the square on the equation and get
(x-6)^2 + (y-6)^2 =36
The circle equation is
(x-h)^2 + (y-k)^2 = r^2
Center(h,k) r=radius
Here we're interested in the circumference: C = pi*d. In this case C = 3.14*(28 inches) = 88 inches.
Now divide this 88 inches into 200 feet to get the # of revolutions ncessary to travel 200 feet.
200 feet 12 in
------------ * --------- = 2400 inches
1 1 ft
2400 inches
----------------------- = 27.2 revolutions (answer)
[ 88 inches/ rev ]
Answer:
0
Step-by-step explanation:
All you have to do is subtract the biggest numbers i the problems.
Number 1 is d.50 because 10= 1 mile and there are 5 miles 10times5=50
