What is the exact circumference of the circle?
cestrela7 [59]

Hello!

What is the exact circumference of the circle?

A.

10π feet  

B.

20π feet  

C.

40π feet  

D.

60π feet

Solving: Using the data  (Circle with center A and diameter of 20 feet labeled).

diameter = 2*radius

20 = 2*r

2\:r = 20

r = \dfrac{20}{2}  

\boxed{r = 10\:ft}

Formula: (Circle length)

\boxed{C = 2* \pi *r}

Now, replace in the circumference length formula:

C = 2\:\pi *r

C = 2\:\pi *10

\boxed{\boxed{C = 20\:\pi\:ft}}\end{array}}\qquad\quad\checkmark

Answer:  

B.  20π feet

\underline{The\:exact\:circumference\:of\:the\:circle\:is\:\:20\:\pi\:ft}

to "show work" just plug in each x value into that equation. you will never learn if all you do is copy down answers. i have given you all of the correct answers, and all you need to do is plug in the values for each x value into the equation, multiply then add. good luck man.

Determine the missing angle in the picture below.
rusak2 [61]

Answer:

x =41.18114952

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

We know the hypotenuse and adjacent sides

cos theta = adjacent / hypotenuse

cos x  = 14.3/19

taking the inverse cos of each side

cos^-1 (cos x) = cos ^-1 ( 14.3/19)

x =41.18114952
