Answer:
The height of the cone is 
Step-by-step explanation:
we know that
The volume of the cone is equal to
where
B is the area of the circular base of the cone
h is the height of the cone
In this problem we have
<em>Find the area of the base B</em>
substitute the value of r
<em>Find the height of the cone</em>
assume 
The correct answer to this question is:
Diameter - B) a segment <span>between two points on a circle that passes through its center radius
</span>
Circumference - <span> F) the distance around a circle
</span><span>
Radius - </span><span>C) Circle A and a line segment connecting points B and C which are on the circle.
</span><span>
secant - </span><span>E) Circle A and a line segment connecting points B and C which are on the circle.
</span><span>
concentric circles - </span><span>D) Two circles that share the same center.
</span><span>
arc - </span><span>A) a piece of the circumference of a circle circumference.</span>

Answer:
The value of x is <u>1</u><u>0</u><u>.</u>
Step-by-step explanation:
By question,
-4(x - 5) = 60
or,-4x + 20 = 60
or,-4x = 60 -20
or, -4x = 40
or, x =40/-4
Hence,x=10
<span>4x + 8y =40
</span><span>4x + 8* 0.8 =40
</span><span>4x + 6.4 =40
</span>4x = 40 - 6.4
4x = 33.6
x = 33.6/4
x = 8.4
