A cylinder fits inside a square prism as shown. For every cross section, the ratio of the area of the circle to the area of the

kolbaska11 [484]

Answer:

Volume of cylinder = $\pi r^2h$

Step-by-step explanation:

Given : A cylinder fits inside a square prism.

To find : The volume of cylinder

Solution : Refer the attached graph.

Area of circle = $\pi r^2$

Area of square = $s^2$

Side of square = diameter of circle= $D^2$

Diameter = 2r

∴ Area of square= $2r^2=4r^2$

$\frac{Area of circle}{Area of Square}=\frac{\pi r^2}{4r^2}=\frac{\pi}{4}$

Area of circle is $\frac{\pi }{4}$ of area of square.

Volume is always = area × height

Volume of prism = Area of square × h = $4r^2h$

Volume of cylinder = Area of circle × h = $\pi r^2h$

Now, rate

$\frac{Volume of cylinder}{Volume of prism}=\frac{\pi r^2h}{4r^2h}=\frac{\pi}{4}$

⇒Volume of cylinder is $\frac{\pi }{4}$ of Volume of prism.

Volume of Cylinder = $\frac{\pi }{4}\times Volume of prism$

Volume of cylinder = $\frac{\pi }{4}\times 4r^2h$

Volume of cylinder = $\pi r^2h$

Given the exponential equation 3* = 243, what is the logarithmic form of the equation in base 10? (5 points)

Andrej [43]

Answer:

$x = \frac{log\ 243}{log\ 3}$

Step-by-step explanation:

Given

$3^x = 243$

Required

Express as a logarithm

$3^x = 243$

Take log of both sides

$log\ 3^x = log\ 243$

Apply the following law of logarithm

$log\ a^b = b\ log\ a$

So, the expression becomes:

$log\ 3^x = log\ 243$

$x\ log\ 3 = log\ 243$

Divide both sides by log 3

$\frac{x\ log\ 3}{log\ 3} = \frac{log\ 243}{log\ 3}$

$x = \frac{log\ 243}{log\ 3}$

Hence, the expression in base 10 is:

$x = \frac{log\ 243}{log\ 3}$ or $x = \frac{log_{10}\ 243}{log_{10}\ 3}$
