Here, use the app photomath.
<h2>
d ≈ 19.1 cm</h2>
<em>Using the formulas</em>
<em>C = 2πr</em>
<em>d = 2r</em>
<em>Solving for 'd' (diameter)</em>
<em>d = C</em>
<em>π = 60</em>
<em>π ≈ 19.09859cm</em>

A right angles is 90 degrees
if you mean 5/4 of the MEASURE of a right angle then
90 times 5/4 (because in math 'of' means multiply)
90 tmes 5/4=450/4=225/2=112.5 degrees
Answer:
12
Step-by-step explanation:
(5x+5)+(115)=180
180-120=60
60/5=12
Answer:
315 degrees
Step-by-step explanation:
Assume that the dial is a perfect circle and therefore makes a full 360 degree rotation. If the dial is already turned 45 degrees, the rotation angle required to return all the way to the initial position is:
![A = 360 - 45\\A=315\ degrees](https://tex.z-dn.net/?f=A%20%3D%20360%20-%2045%5C%5CA%3D315%5C%20degrees)
You will need to rotate 315 degrees.
