Answer:
Mid point of the given end points = 
Step-by-step explanation:
Given the end points of the line segment are :
(0,
) & (
,0)
We will use the mid point formula when two points are: (x₁,y₁) & (x₂,y₂)
mid point = 
now put the value of x₁ = 0
x₂ = 
y₁ = 
y₂ = 0
mid point = 
= 
That's the final answer.
3 x + 7 = 2
3 x = 2 - 7
3 x = - 5
x = - 5/3
3 ( -5/3) + 7 = - 15/3 + 7 = - 5 + 7 = 2
Volume of a cone = pir^2h/3
so substitute what you know
1,102.14 = 3.14(r^2)(13/3)
divide by 3.14
351 = r^2(4.3333)
divde by 13/3
81 = r^2
r = 9 inches
