# What is a conical pile

## What is the volume of a conical pile?

The formula for the volume of a cone is

**V=1/3hπr²**.## How do you find the height of a conical pile?

## What type of differentiation is used to discover the equation that relates quantities rates of change to each other?

Use

**differentiation**, applying the chain rule as necessary, to find an equation that relates the rates. Be sure not to substitute a variable quantity for one of the variables until after finding an equation relating the rates.## How do you measure a cone?

Cone volume formula

A cone is a solid that has a circular base and a single vertex. To calculate its volume you need to **multiply the base area (area of a circle: π * r²) by height and by 1/3:** **volume = (1/3) * π * r² * h**.

## What part of the cylinder is a cone?

circular base

A cone is a three-dimensional solid that has a circular base joined to a single point (called the

…

Surface Area of a Cone.

**vertex**) by a curved side. You could also think of a cone as a “circular pyramid”. A right cone is a cone with its vertex directly above the center of its base.…

## What does Dr mean in calculus?

In calculus, the

**differential**represents the principal part of the change in a function y = f(x) with respect to changes in the independent variable.## How do derivatives relate to maximum and minimum values?

One of the great powers of calculus is in the determination of the maximum or minimum value of a function. … The derivative

**is positive when a function is increasing toward a maximum, zero (horizontal) at the maximum**, and negative just after the maximum.## How is rate of change used in real life?

Other examples of rates of change include: A population of rats increasing by 40 rats per week. A car traveling 68 miles per hour (distance traveled changes by 68 miles each hour as time passes) A car driving 27 miles per gallon (distance traveled changes by 27 miles for each gallon)

## How do we solve problems involving related rates?

In all cases, you can solve the related rates problem by

**taking the derivative of both sides, plugging in all the known values (namely, x, y, and ˙x), and then solving for ˙y**. To summarize, here are the steps in doing a related rates problem: … Take d/dt of both sides.## How do you solve logarithmic differentiation?

## Why do we use related rates?

Related rates come in handy when we have two related quantities and one of

**their rates of change is much harder to find than the other one**. For example, look at the figure below, you can see that it is difficult to find the rate of change in radius of the balloon while it is being pumped up.## Is D DX a fraction?

So, even though we write dydx as if it were a fraction, and many computations look like we are working with it like a fraction,

**it isn’t really a fraction**(it just plays one on television). However… There is a way of getting around the logical difficulties with infinitesimals; this is called nonstandard analysis.## What does F X mean?

f(x) means

**function of x**. For x any number, f(x) depends on the value of x. Example: If f(x) = x + 2 and x = 6 then f(x) or f(6) = 6+2 = 8. Example: If f(x) = x^2 -1 and x = 5 then f(5) = 5^2 -1 =25 -1 = 24. In each case x is a variable input.## What is dx and dy?

d/dx is an operation that means “

**take the derivative with respect to x”**whereas dy/dx indicates that “the derivative of y was taken with respect to x”.
