Answer:
7.1 (7.06 rounded to the tenth)
Step-by-step explanation:
The formula for Area of a Circle is: π·r²
R = Radius
π = pi, or 3.14
As long as you know the formula, this is easy!
In class, you may have already been told that the radius is half of the diameter.
1. Half of 3 ft is 1.5 ft.
2. Plug 1.5 in for r, in your calculator
3. Do the calculation, and you should come out to get 7.06858347058
4. Round it!
Finding area for a circle is satisfying, isn't it? xD
I don't understand this... please help :(
Answer:
Radius is the distance from the center of the circle to the edge (if you were to cut just a slice of pizza)
diameter is directly in the middle from one end to the other (if you were to cut the pizza in half)
this means that the diameter is DOUBLE the radius
circumference is the length of the outside of the circle (so the length of the pizza crust)
this one is tricky because to find circumference you need to do [tex]2\pi r[/tex] (r is the value of the radius)
so for problem 1 the radius is 3 cm (the line is equivalent to if you were trying to cut out one slice of pizza)
the diameter is DOUBLE the radius, so if you were to cut the pizza in half all the way it would be 6 cm
and the circumference ([tex]2\pi r[/tex]) is 2 * pi * 3 cm
because it says to round pi to 3.14, the circumference would be 18.84
lmk if this wasn't a good explanation or if you want help on the other problems too

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Write and solve an equation to find the answer. From midnight to 6:00 am, the temperature rose 8°C. At 6:00 am, the temperature was − 20 ° C. What was the temperature at midnight?
Answer: -28 degrees Celsius
Step-by-step explanation:
Equation: -20 = t + 8 or t = -20 + -8 (t represents the temperature at midnight).
Using the second equation given, add the two numbers together. Since adding a negative is the same as subtracting a positive, subtract 20 from 8 and make it negative. The answer is -28.
How do you solve these problems using Two-Step Equations. You will get 65 points if correct.

Stan ran 4 and 4 7/10 miles, which was 1 and 3 Over 10 fewer miles than Matt ran. Four students wrote and solved equations to find m, the number of miles that Matt ran. Which student wrote and solved the equation correctly?
Possible Answers:
Answer:
Matt ran 6 miles.
Step-by-step explanation:
Stan ran 4 and 7/10 miles, and this is 1 and 3/10 fewer miles than Matt.
this means that Matt ran the following amount of miles
4 and 7/|0 + 1 and 3/10 miles:
(4 + 1) + (7/10 + 3/10) = 5 + 10/10 = 6 miles.
This would be the correct way to solve this equation.

I really need help ASAP!!I am just now doing my schoolwork for today, due to some distractions, can someone help me understand how to find the volume of basic shapes? I really need help, because I have been talking to someone most all day, and I need to finish a sheet about shapes' volume. If you could right the formula for that, that would be great.
answer:
so the basic formula to find volume in shapes would be length × width × height.
here is a example : ( i cant really make the shape 3D so lets just say it is )

all you really need to do is multiply all of them together, for smaller numbers you shouldn't have to really use your calculator ( if you have a pretty good memory of your times tables then you shouldn't have to as least ) but with bigger numbers then i would recommend using your calculator if your teacher does lets you

What is the shape of the distribution shown below?
Answer: its B they come from both sides
The shape of the graph indicates that the distribution is symmetrical. The correct answer is B
As we know that skewness is a measure of a distribution's asymmetry and can be positive (right-skewed), negative (left-skewed), or zero (symmetrical).
The center of the distribution is depicted in the graph. This signifies that the distribution's tail extends to the middle, and the majority of the data is concentrated on the graph's middle side.
Here, the majority of the data is between 0 and 50, and there are fewer data points between 50 and 100. This creates a long tail on the middle side of the graph, indicating that the distribution is symmetrical.
Therefore, the correct answer is B: The distribution is symmetrical.
