Answer:
Height = 4.78 unit approximately
Step-by-step explanation:
Volume of a one is given by the formula 1/3πr²h
So given that yhe volume of this cone is equal to 320Tr units
And the radius is 8 units.
Lets determine the height of the cone.
V= 1/3πr²h
But V = 320
r = 8
320 = 1/3((3.14)(8)²h
(320*3)/(3.14*64)= h
960/200.96= h
4.777= h
h = 4.78 unit approximately
Answer:
C
Step-by-step explanation:
do that with pithagoras:
20² + 4,5² = x²
400 + 20,25 = x²
420,25 = x²
x = 
x ~ 20,5
Letter C: 20,5 feet
A*25+b*35=10250
a +b = 350 | * -25
25a + 35b= 10. 250
-25a -25 b= -8.750
------------------------------
10b = 1500
b=1500:10
b=150 tickets cost 35 $
a= 350-150
a= 200 tickets cost 25 $
We know that equation of a parabola is given by :-
y = a(x-h)² + k
Where (h,k) is the vertex of parabola and (x,y) is any point on its curve.
Given that vertex of parabola is (3,5) and one point (x,y) is (6,-1).
We can plug the given information in the equation of parabola and solve it for value of 'a' :-
-1 = a(6 - 3)² + 5
-1 = a(3)² + 5
-1 = 9a + 5
9a = -1 -5 = -6
a =
a =
is the final answer.
