For this case we have that by definition, the circumference of a circle is given by:

C = \pi * d

Where:

d: It is the diameter of the circle.

d=2r

Clearing we have:

C=2\pi*r\\r=\frac{C}{2\pi}\\r=\frac{106.81}{2\pi}\\r=17,0079

Rounding the amount and \pi=3.14

Then, the radius of the circle is 17 centimeters

ANswer:

r = 17 \ cm

<u>Answer:</u>

r = 16.9 cm

<u>Step-by-step explanation:</u>

We are given the circumference of a circle to be 106.81 cm and with the help of this, we are to find the radius of the circle.

We know that the formula for the circumference is given by:

2\pi r

so equating the given value to get:

2 \pi r = 106.81

r = \frac { 106.81 } { 2\times \pi }

r = 16.9 cm

Someone help please this is for trigonometry
Softa [21]
Hi there!

Something really good to remember about trigonometry is SOHCAHTOA. I won’t dive into too much detail about it, but you should google it for future assignments.

Anyways,

tan50°=14/AB
ABtan50°=14
AB=14/tan50°
AB=11.75

cos50°=14/AC
ACcos50°=14
AC=14/cos50°
AC=21.78

For the measure of angle C you can use a theorem called the third angle theorem. In every single possible triangle, the sum of all three angles adds up to 180°. You can set up an equation like so...

angleC=180-(90+50)
angleC=180-140
angleC=40°

Please help me! I need to find what the measure of angle VTS is​
spayn [35]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Adjacent angles total to 180 degrees

15x + 1 + 13x + 3 + 64 = 180

28x + 68 = 180

Subtract 68 from both sides:

18x = 112

Divide both sides by 28:

x = 4

Substitute this value back in:

15(4) + 1 = 61

Angle VTS = 61 degrees

➶ Hope This Helps You!

➶ Good Luck (:

Lin was looking at the equation 2x − 32 + 4(3x − 2462) = 14x.
Vesna [10]

Answer: Lin is correct but her thinking is wrong.

Step-by-step explanation:

2x-32+4(3x-2462)=14x

First solve parentheses: 2x-32+12x-9842=14x (you distribute the 4).

Then add common factors on the same side of the equal signs:

14x-9880=14x

When solving for x you would subtract 14x giving you:

-9880=0 which would never be true.
