Volume of a cylinder is $\pi r^2h$ , where r is the radius and h is the height.

This comes from the area of a circle being $\pi r^2$ . A cylinder is the area of the base circle multiplied by its height.

Using this formula, the volume of the given cylinder is
$\pi r^2(3r) \\
= 3 \pi r^3$

What is the length of the hypotenuse, c? Round your answer to the nearest hundredth.

BartSMP [9]

Answer:

c=11.180

Step-by-step explanation:

formula to find the hypotenuse (c)= a^2+b^2=c^2

so... 10^2+5^2=c^2, please correct me if I'm incorrect, or made a mistake

100+25=c^2

125=c^2

square it and you get...

c=11.18033988...

c=11.180

Solve for x, log(5x-5)=log(2x+3)+log(15)

Liono4ka [1.6K]

$\log(5x-5)=\log(2x+3)+\log15\\
\log(5x-5)=\log[15(2x+3) ], \text{ because } \log(ab)=\log a+\log b\\
\log(5x-5)=\log(30x+45)\\
5x-5=30x+45, \text{ because } (\log x=\log y\rightarrow x=y.)\\
-25x=50\\
\text{Then } x=-2.$

y= 3

x= 1

Step-by-step explanation:

7x+y=10

3x-2y= -3

solve the equation

y=10-7x

3x-2y= -3

substitute the value of y into an equation

3x-2(10-7x)= -3

distribute

3x-20-14x= -3

add 14x from both sides

17x-20= -3

add 20 from both sides

17x=17

divide both sides by 17

x=1

substitute the value of x into an equation

y=10-7•1

multiply 7 to 1

y=10-7

subtract

y=3
