Answer:
Radius, r, is 3.75
Step-by-step explanation:
From the given diagram,
AB = 9
AC = 6 + r
BC = r
Thus applying the Pythagoras theorem, we have;
= 
+ 
= 
+ 
36 + 12r + = 81 +
collecting like terms,
12r = 81 - 36
12r = 45
r = 
= 3.75
r = 3.75
The radius is 3.75.
Answer: (3, -2)
Step-by-step explanation:
The vertex is the highest or lowest point of a parabola, and I found it. Hope this helps :)
Diameter = 7 cm
radius = 7÷2 = 3.5
Volume of cone = 1/3
Volume of cone = 1/3
= 115 cubic inches (Answer B)
Answer:
x = 88
Step-by-step explanation:
All angles in a triangle equal 180 degrees. So our equation will be:
x + 48 + (x - 44) = 180
x + 48 + x - 44 = 180
2x + 48 - 44 = 180
2x + 4 = 180
2x = 176
x = 88
Hope this helps!
