The circle with center O has a minor arc BSA with a length of

tangare [24]

Answer:

D. $\frac{27\pi}{2}$ inches.

Step-by-step explanation:

We have been given that the circle with center O has a minor arc BSA with a length of $3\pi^{2}$ inches. The central angle is 40°.

To find the circumference of circle we will use formula:

$\frac{\text{Central angle}}{2\pi}=\frac{\text{Arc length}}{2\pi r}$ , where $2\pi$ = measure of 360 degrees in radians and $2\pi r$ = circumference of circle.

Let us convert measure of central angle into radians.

$40^{o}=\frac{40*\pi}{180} =\frac{2\pi}{9}$

Upon substituting our given value in the formula we will get,

$\frac{\frac{2\pi}{9}}{2\pi}=\frac{\frac{3\pi}{2}}{2\pi r}$

$\frac{2\pi}{18\pi}=\frac{3\pi}{4\pi r}$

$\frac{1}{9}=\frac{3}{4r}$

Cross multiplying we will get,

$4r=27$

$r=\frac{27}{4}$

Hence, the radius of our circle is 27/4 inches.

Since the circumference of circle is $2\pi r$ . Upon substituting $r=\frac{27}{4}$ we will get,

$2\pi r=2\pi* \frac{27}{4}=\frac{27\pi}{2}$

Therefore, circumference of our given circle will be $\frac{27\pi}{2}$ inches and option D is the correct choice.

41= 5x+17-3x need please

sergey [27]

Answer:

${\huge{\pink{\underline{\underline{Solution}}}}}$

41=5x+17-3x

41=5x-3x+17

41=2x+17

41-21=2x

2x=20

$x= \frac{20}{2}$

Hence,value of x=10

How do you use the additive inverse to evaluate an expression that uses subtraction ?<br>

AlladinOne [14]

To use the additive inverse to evaluate an expression that uses subtraction, change the sign of the number to positive

<h3>What is additive inverse?</h3>

Additive inverse is simply changing the sign of a number and then adding it to the original number to get an answer that is equal to 0.

The additive inverse of a number is another number

The additive inverse of number 3 is - 3

For an expression that uses subtraction, to use the additive inverse, change the sign of the number to positive

Thus, to use the additive inverse to evaluate an expression that uses subtraction, change the sign of the number to positive

What is the lowest common denominator of 1/12 & 1/15

Lesechka [4]

Well lets think of the first number that can fit 12, well 60 works right?? 12 fits in 60 5 times does it work with 15, yes it does, 15 fits in 60 4 times, but is that our smallest number lets check it our lets ssubtract 12 from 60, it is 48 is there a number that multioplied by 15 that can give you 48?? NO!! lets subtract 12 more this gives u 36 can something fit? NO! lets take 12 more and get 24 does anything multiplied by 15 give you 24?? No! so our smallest number would be 60 because nothing else can work for both of this nubers

Hope this helps
