Answer:
r = 14.5
Step-by-step explanation:
AD is the perpendicular bisector of chord EC, so is the diameter of the circle. The radius is half the diameter.
r = AD/2 = (AB +BD)/2 = (25 +4)/2 = 29/2
r = 14.5

Segments BE and BC are 10 = √(25·4)
Answer:
7672.50
Step-by-step explanation:
7500×0.23%=17.25
17.25×10=172.50
7500+172.50=7672.50

for 7 & 8 you use the equation
![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20)
your points are (3,8) & (9,5)
so you plug the numbers in
y2= 5
y1=8
x2=9
x1=3
you subtract them get a fraction and that is your slope
9 & 10
use the equation
![y - y1 = m(x - x1)](https://tex.z-dn.net/?f=y%20-%20y1%20%3D%20m%28x%20-%20x1%29)
plug you numbers in for y1 and x2 m is your slope plug it in and that is your equation
