The dot product of u with itself is 24. what is the magnitude of u?

Step-by-step explanation:

We have been given that the dot product if u with itself is 24.

Now, we know that the dot product of vector a and b is given by

Here, is the angle between the vectors a and b.

We have to find the dot product of u with itself. Hence,

a = u

b = u

Thus, dot product is given by

Thus, the magnitude of u is

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

answer: haha (: i’ll go see what it is
