Answer:
Step-by-step explanation:
The volume of a cylinder is expressed as
V = πr^2h
Where
π is a constant
h is the height of the cylinder
The volume of a cone is expressed as
V = 1/3πr^2h
Where
π is a constant
h is the height of the cone
If the cylinder and a cone have congruent bases and the same volume, it means that
πr^2h = 1/3πr^2h
πr^2 cancels out on both the left hand side and right hand side of the equation. It becomes
h = h/3
It means that the height of the cone is 3 times the height of the cylinder. Therefore,
If height of cylinder = 4 cm, height of cone = 12 cm
Step-by-step explanation:
1-
calculate the powers behind the brackets from left to right
2-
Calculate the powers (a power squared means the number times itself so 2 squared equals 4)
3-
Calculate the sum ( minus minus equals plus so for example 4- -5= 4+5=9)
4- 49+5+2= 56
Answer:
Although New Orleans is usually credited with being the birthplace of jazz, similar music also began happening not long after in other cities, including Chicago, Kansas City, and Saint Louis.

Answer:
slope = 2
y-intercept= -4
Step-by-step explanation:
slope = y2- y1/ x2-x1
slope = 4-(-4) / 4-0
slope = 2
using (4,4) for (x,y)
y= mx+b
4= 2(4)+b
b= -4

Step-by-step explanation:
To graph the inequality y>3, we have to graph the corresponding linear equation, y=3 with a dashed line.
We then shade above to obtain the graph of the corresponding inequality y>3.
The graph is shown in the attachment.
