Answer:
h=8cm
Step-by-step explanation:
V= πr^2h/3
Where
V=volume of a cone
π=pi= 3.14
r= radius=4cm
h= height = ?
V= πr^2h/3
134= 3.14*4*4*h/3
134= 50.24h/3
Divide both sides by 50.24
h/3= 134 / 50.24
h/3= 2.67
Cross product
h= 2.67*3
h= 8.01
Approximately h= 8cm
The best estimate of the cone's height is 8cm
Answer:
28=x
78=y
Step-by-step explanation:
The lines are perpendicular so 78 would be the same for the top line. So the equation fill in would be (5x-62)=78 turning x into 28
Answer:
126
Step-by-step explanation:
The way for you to find a triangle angles is by having an answer to 180. That 180 is called supplementary. 126+54 = 180.
Answer:
(4, 4)
Explanation:
- I have solved it using graph.
(4, 4) is the only point which lies inside both of the inequalities.
