Answer:
x = 5
Step-by-step explanation:
The length of line segments joining a common point to tangents are always equal.
RS = RQ = 2
PW = PQ = 3
x = PQ + QR = 3 + 2 = 5
Answer:
Step by step:
To get the derivative you can either multiply out the product (which I did below), or apply the formula for the derivative of a product of two functions. Either way you will obtain the same result, of course.
Answer:
0 to 10
Step-by-step explanation:
Answer:
Height = 7 meters
Step-by-step explanation:
Equation:
To work out the height, you need to know the formula for the volume of a cone which is:
Explaining variables:
- mathematical constant.
- radius of the cone
- height of the cone
- volume of the cone
Working out the height:
We are looking for the height, so let's re-arrange the equation.
We are given the height, volume and diameter.
To work out the radius we have to know that . So the radius is m.
Now let's put everything in the equation for the height to work it out.
meters.
Therefore, the height of the cone is 7 meters.
