Answer:
Okay so you first need to figure out what your variables are in the equation given. It tells you pi is 3.14. on the top of the cylinder it shows that the radius (r) is 2. the height (h) is shown on the cylinder as 4. Now all you have to do is plug in the values for the variables into your calculator. You have (2) times (3.14) times the radius (2) and you square the radius. then you add (2) x (3.14) x (2) x (4). So if you put it in your calculator it would look like this: (2)(3.14)(2)^2+(2)(3.14)(2)(4)=75.36 Your answer is 75.36
Answer:
either x or y must equal 0
Step-by-step explanation:
ts given that xy = 0
Remember that product of two numbers can be zero only if:
Both of them are zero or Either of them is zero as zero multiplied to any non-zero number will always be equal to zero. This is known as Zero Product Property.
So, if the product of x and y is equal to 0 there are two possibilities:
Both x and y are equal to 0
Either x or y must be equal to 0
Note that the condition both x and y are equal to zero is not a must condition, because even if one of them is equal to zero, the entire expression will be equal to zero.
Hence, the condition which has to be true in all cases for xy = 0 is:
either x or y must equal 0
As we know the formula to calculate the line of equation is y - y1 = m (x - x1)
Where m is the slope. y1 is the first y co ordinate. x1 is the first x co ordinate.
Now we do know that the slope of parallel line is the same as the slope of the original line.
So parallel line slope is 3 so slope for our line is 3. Hence equation is y - 7 = 3 (x - 2) which becomes y = 3x + 1.
