Answer:
Step-by-step explanation:
Perimeter = 2(l + w)
l = 8.5cm, perimeter = 24cm
24 = 2(8.5 + w)
Dividing through by 2
24/2 = 8.5 + w
12 = 8.5 + w
W = 12 - 8.5
W = 3.5cm
Step-by-step explanation:
The center of a circle with 2 end points of a di diameter is the midpoint of the two endpoints.
The formula needed to find the minpoints is
(x,y) = (x2 + x1)/2, (y2 + y1)/2
x2 = 3
x1 = 3
y2 = 0
y1 = -7
midpoint = (3 + 3)/2, (0 - 7)/2
midp[oint = 3,-3.5
The midpoint is the center of the circle. Observe that the signs get changed when entering the values for (x,y)
So far what you have is (x - 3)^2 + (y + 3.5)^2 = r^2
To determine r^2 you need only take the distance from the center to oneof the endpoints.
r^2 = (3 - 3)^2 + (3.5 - 0)^2
r^2 = 3.5^2
r^2 = 12.25
Answer: (x - 3)^2 + (y + 3.5)^2 = 12.25

9.42 is the circumference, for future refernce its just pi times diameter :)
