Answer:
The volume of the cone is 12936 cubic mm.
Step-by-step explanation:
Given
Circumference of base = 132 mm
Height of the cone = 28 mm
Solution
Formula of circumference =
= 132 mm

Now volume of cone = 
on substituting the value of r and h we get ;

thus volume of cone is 12936 cubic mm.
Answer:
? Is 41 degrees
Step-by-step explanation:
SOH CAH TOA
Hypotenuse is 60
Adjacent is 45
Hypotenuse and adjacent - Cos
(Cos inverse to find the angle)
Cos(?) = a/h
Cos(?) = 45/60
Cos-(45/60) =?
? = 41.40962211
Hope this helps!
Answer:
See explanation and hopefully it answers your question.
Basically because the expression has a hole at x=3.
Step-by-step explanation:
Let h(x)=( x^2-k ) / ( hx-15 )
This function, h, has a hole in the curve at hx-15=0 if it also makes the numerator 0 for the same x value.
Solving for x in that equation:
Adding 15 on both sides:
hx=15
Dividing both sides by h:
x=15/h
For it be a hole, you also must have the numerator is zero at x=15/h.
x^2-k=0 at x=15/h gives:
(15/h)^2-k=0
225/h^2-k=0
k=225/h^2
So if we wanted to evaluate the following limit:
Lim x->15/h ( x^2-k ) / ( hx-15 )
Or
Lim x->15/h ( x^2-(225/h^2) ) / ( hx-15 ) you couldn't use direct substitution because of the hole at x=15/h.
We were ask to evaluate
Lim x->3 ( x^2-k ) / ( hx-15 )
Comparing the two limits h=5 and k=225/h^2=225/25=9.
I will go with B.
