The diameter of a cylinder is 4 centimeters. The height is 12 centimeters. Using 3.14 for pi, what is the volume of the cylinder
Dovator [93]

Answer:

The volume of the cylinder with given height and radius is 150.72 centimeters³ .

Step-by-step explanation:

Given as :

the height of cylinder = H = 12 centimeters

The diameter of cylinder = D = 4 centimeters

So The radius of cylinder = R = \dfrac{\textrm Diameter}{2}

Or, R = \frac{4}{2}

I.e R = 2 cm

The volume of cylinder is given as V = \pi×R²×H

where R is the radius and H is the height

So, V = 3.14×(2)²×12

Or, V = 3.14×48

∴ V = 150.72 centimeters³

So, The volume is 150.72 centimeters³

Hence The volume of the cylinder with given height and radius is 150.72 centimeters³ . Answer

What’s the mean, variance and standard deviation
Tom [10]

Answer:

Step-by-step explanation:

binomial distritubtion

mean= n*p

.23*300= 69

variance= n*p*(1-p)

.23*300*(1-.23)=53.1

standard deviation= sqrt(variance)

sqrt(53.13)= 7.3

Identify the type of function represented by f(x)=1/2(3)^x
Firlakuza [10]

The function represented by f(x) = (1/2)(3)ˣ is an exponential growth

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.

The independent variable in the function f(c) = 2c + 9 is c whereas the dependent variable is f.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.

An exponential function is in the form:

y = abˣ

Where a is the initial value and b is the multiplication factor.

If b > 1, it is an exponential growth but if b < 1, it is an exponential decay.

Given the function:

f(x) = (1/2)(3)ˣ

since 3 > 1, it is an exponential growth.

The function represented by f(x) = (1/2)(3)ˣ is an exponential growth
