Answer:
When using the given information, the diameter of the circle is going to be 28 mL.
Step-by-step explanation:
First, we need to know the formula for finding the area of a circle.
[tex]Area=r^2\pi[/tex]
Now, we need to rearrange the formula so we can find the radius.
[tex]Radius=\sqrt{\frac{A}{\pi} }[/tex]
Next, we plug in the given area into the equation.
[tex]Radius=\sqrt{\frac{615}{\pi}}[/tex]
[tex]Radius=\sqrt{196}[/tex]
[tex]Radius=14[/tex]
Now that we have the radius, we can find the diameter. The radius is half the length of the diameter. So, in order to find the diameter, we have to multiply the radius by 2.
[tex]14 * 2=28[/tex]
So, the diameter of the circle is 28 mL

[tex]20\pi units^3[/tex]
Step-by-step explanation:
Answer:
V = 62.8 units³
Step-by-step explanation:
Once the area of a circle is:
[tex]A=\pi r^2[/tex]
The volume of a cylinder is:
[tex]V=\pi r^2 h[/tex]
where [tex]h[/tex] is the height of the cylinder.
Once, [tex]r=2 \text{ and } h=5[/tex]
[tex]V=3.14 \cdot 2^2 \cdot 5\\V=3.14 \cdot 20\\V=62.8 \text{ units cubed}[/tex]

Answer:
The height of trapezoid is 7km.
Step-by-step explanation:
Given that the area of trapezoid formula is A = 1/2×(a+b)×h where a and b represents the length and h is the height. By substituing the values, you are able to find the height :
[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]
Let a = 4km,
Let b = 8km,
Let area = 42km²,
[tex]42 = \frac{1}{2} \times (4 + 8) \times h[/tex]
[tex]42 = \frac{1}{2} \times 12 \times h[/tex]
[tex]42 = 6 \times h[/tex]
[tex]6h = 42[/tex]
[tex]h = 7 \: km[/tex]
Answer: 7km

Answer: D
Step-by-step explanation:
A and C are linear equations therefore we can eliminate them.
We are left betwen C and D.
C.
x²=25
x=5, x=-5
For C, we can eliminate because when you solve for x, you get 2 linear equations. You may see the x² and think it's linear, but when you solve it, you get 2 linear equations.
We are left with D. Even if you graph it and it doesn't look like a parabola or quadratic, it is still a quadratic equaiton. The 1/ makes it split both ways.

Answer:
10/3
Step-by-step explanation:
6 length is 2 height.
So 10(6+4) length is 10/3 height
Answer:
x = 10/3
Step-by-step explanation:
These two triangles are similar by AA similarity, as they share angle A, and both have right angles.
Not we can set up a ratio:
6/(6+4) = 2/x
6/10 = 2/x
3/5 = 2/x
Multiply both sides by 5x,
3x = 10
Divide both sides by 3:
x = 10/3
Zeke goes to a skate shop with his friend Tristan. Tristan buys a helmet that costs $28.75. Zeke finds a helmet that is [tex]\frac{3}{5}[/tex] of the cost of Tristan's helmet. If Zeke gives the cashier a $20 bill, how much change will he receive.
Answer: $2.75
Step-by-step explanation:
Zeke's helmet cost 3/5 x 28.75 = 17.25
Change = 20 - 17.25 = 2.75

The given functions are y=3x² and y=x².
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The graph for the given functions can be determined as follows
To find the transformation, compare the expression to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Horizontal Shift: None
Vertical Shift: None
Reflection about the x-axis: None
Reflection about the y-axis: None
