If the cone’s radius is 1, what is its height?
If the cone’s radius is 2, what is its height?
If the cone’s radius is 5, what is its height?
If the cone’s radius is 12, what is its height?
If the cone's radius in r, then what is the height?
Im so confused on how to start
Answer:
r=1, h=9
r=2, h=2.25
r=5, h=0.36
r=12, h=0.0625
r=r, h=9/r²
Step-by-step explanation:
Volume of a cone = πr²h/3
3π=πr²h/3
r²h=9
when r=1?
r²h=9
1²h=9
h=9
when r=2?
r²h=9
2²h=9

h=2.25
when r=5?
r²h=9
5²h=9
25h=9
h=0.36
when r=12?
r²h=9
12²h=9
144h=9
h=0.0625
when r=r?
r²h=9
h=9/r²
The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.
VolumeVolume is the amount of space that is occupied by a three dimensional object.
The volume of a cone (V) is given by:
V = (1/3)πr²h
Where r is the radius and h is the height.
For a radius of 1:
3π = (1/3)π*(1)² * h
h = 9
For a radius of 2:
3π = (1/3)π*(2)² * h
h = 2.25
For a radius of 5:
3π = (1/3)π*(5)² * h
h = 0.36
For a radius of 12:
3π = (1/3)π*(12)² * h
h = 0.02
The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.

It snowed 40% more this year than it did last year. If it
snowed 45 inches last year, how much did it snow this
year?
a) In the sketch box, draw a diagram to represent this
situation.
b) In the answer box, write a simplified equation to
represent this situation. Use "y" to represent the
amount of snowfall this year. Your equation should use
decimals.
Answer: y= .4 times 45
it snowed 63 inches
Step-by-step explanation: (I can’t write a diagram on here)
pls mark brainliest
We can conclude that -
The amount snowed this year is 63 inches.A simplified equation to represent this situation -y = 45 + {40% of 45}What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that it snowed 40% more this year than it did last year. It
snowed 45 inches last year.
{ 1 } -
The amount snowed this year would be -
{x} = 45 + (40% of 45)
{x} = 45 + (40/100 x 45)
{x} = 45 + 18
{x} = 63
{ 3 } -
A simplified equation to represent this situation -
y = 45 + {40% of 45}

The product of (3 - 4) and (blank)
is 25.
Answer:
-25
Step-by-step explanation:
Since product mean multiply, we multiply (3-4) and (blank), which we'll call "n".
(3-4)n = 25
subtract in parentheses
(-1)n = 25
remove parentheses
-1n = 25

A triangle has a base of 10 centimeters and a height of 12 centimeters. A rectangle has a base of 10 centimeters and a height of 12 centimeters.
What are the areas of the figures?
The area of the triangle is
___ cm2.
The area of the rectangle is
___ cm2.
The area of the triangle is
60 cm2.
The area of the rectangle is
240 cm2.
In a two-dimensional plane, an area of triangle is equal to the sum of the areas of its three sides.
To calculate a rectangle's area, count the number of square units that fit within the rectangle's perimeter.
Area of triangle = h x b / 2
Given
h = 12
b =10
hence
A= h x b / 2
= 12 x 10 / 2
= 120 / 2
= 60 cm2
Area of rectangle = l x b
Given
l = 12
b = 10
hence
area of rectangle = l x b
= 12 x 10
= 120 cm2

Jon is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by h(t)=5+25t-16t^2, where t is the time in seconds.
a) How much time will pass before Jon hits the ball? (round to the nearest tenth of a second)
b) What is the time in which the maximum height the ball attains? ( to the nearest hundredth of a second)
Answer: A= 1.60 sec
And I am not sure if B is correct, but I got 14.77 ft.
Step-by-step explanation:
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Jon who is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by -
h(t) = 5 + 25t - 16t²
where [t] is the time in seconds.
[A] -
At h = 4ft, we can write -
4 = 5 + 25t - 16t²
- 16t² + 25t + 1 = 0
On solving, we get -
t = 1.602 seconds
[B] -
We have -
h(t) = 5 + 25t - 16t²
For maximum height -
dh/dt = 0
d/dt(5 + 25t - 16t²) = 0
0 + 25 - 32t = 0
32t = 25
t = 25/32
t = 0.79 seconds
Therefore -
t = 1.602 seconds will pass before Jon hits the ball.At t = 0.79 seconds the ball attains maximum height.To solve more questions on Equation Modelling, visit the link below -

do 252/448 and 36/64 form a proportion?
Answer:
252/448 and 36/64 form a proportion
Step-by-step explanation:
The easiest way to do this is to let 252/448 = 36/64
Then cross multiply to get 252(64) = 36(448)
16128 = 16128
Since the two products are equal, then 252/448 and 36/64 form a proportion. If the the two products were unequal, then the two fractions would NOT form a proportion.

Answer:
5^2+h^2=12^2, the answer would be ~10.97 ft.
Step-by-step explanation:
I would use the Pythagorean theorem to solve this problem. Put in the things that you know, so in this image we are given one of the legs and the hypotenuse of the triangle.
Pythagorean theorem is :
a^2+b^2=c^2 with a and b being the legs and c being the hypotenuse.
Once you plug in the hypotenuse and one of the legs, solve for the other leg by subtracting a^2 (5^2) from 12^2 (c^2), which will give you 119, and then take the square root of 119 and you will get your answer.
