Not as hard as you think.
Just multiply all the prime factors together.
I agree the answer is 225 and you can also use the calculator too.
Answer:
A' = (5,7)
Step-by-step explanation:
So, we start with the original point A at (3,1), that means x = 3 and y = 1.
We move it 2 units to the right... so we're moving along the X-axis... and we're moving to the right.. so we're increasing the value of x. That means starting with x = 3, we go 2 more units... we then get to x = 5.
In the same way, we move 6 units up... so we move along the Y-axis. We go up, so we also increase the value of y. Starting with y = 1, we move up by 6 units... so we are now at y = 7.
A' point is then at (5,7).

Answer:</h2>
one cone within the cylinder.
<h2>
Step-by-step explanation:</h2>
First of all we have to start with half of a sphere (also known as a hemisphere), whose radius is r, and calculate its volume. Then we can double our answer at the end to find the volume of the complete sphere. But first to apply the Cavalieri's Principle, we start with a cone with the same radius r and suppose the height is also r, so the volume of this cone is:

Next, let's look at a cylinder and suppose this cylinder also has a radius r and height r, so the volume of this cylinder is:

Next, we place the the cone inside the cylinder and the volume that's inside the cylinder, but outside the cone is:

And this is the volume of a hemisphere. Finally, if we double this value we get the volume of a complete sphere, which is:
