On plotting the above mentioned points we get a right angled triangle.
On rotating this about y axis we obtain a cone.
Hence your answer is cone.
Hope this helps.
Unit circle is the circle with radius of 1. Therefore, the circumference of the unit circle is 2pi*r. R equals to 1, so the circumference is just 2pi
I think the first is 107 and the second is 2. i’m not sure about the last two blanks but if they’re asking if it’s equivalent or not i think it is
<span>In order to find the standard deviation, we first have to calculate the mean (average) of the numbers. To get this we add all the numbers together and then divide by 12 since there are 12 numbers. The mean = 782. Next, we take each number and subtract the mean, taking the result and squaring it. For this we get: 6724, 2209, 10404, 11664, 729, 1764, 12544, 9, 529, 71824, 1444, 1024. Now we sum all of these up and take the average by dividing the sum by 12. Doing this we get 120868/12=10072. The last step is the take the square root of that number to get the standard deviation. The final result is 100.</span>
