Answer:

$\frac{C}{2\pi } =r$

Step-by-step explanation:

Recall to find the circumference of a circle the formula is $C=\pi d$ or $C=2\pi r$ . Since we need r, we will use the second formula for circumference.

We start by solving for r in the Circumference formula. using inverse operations. We divide both sides (as the inverse of multiply) by 2pi.

$C=2\pi r\\\frac{C}{2\pi } =r$ .

Lapatulllka [165]

115°
A triangle is 180° so add the two degrees given and subtract that from 180; 180-(75+40)
180-155= 65. then a line is 180 degrees so you subtract 65 from 180 and get 115
