You don't have to use a formula, all you have to do is use basic algebra to modify the equation in front of you. Simply divide both sides by 2pi and you will end up with C/2pi = r. Then, just type it into your calculator and you're good to go!
Answer:
GH = 7![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = ![\frac{1}{\sqrt{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%7B2%7D%20%7D)
sin45° =
=
=
=
( cross- multiply )
GH = 7![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)

Answer:
Approx. 423.88 feet squared
Step-by-step explanation:
Let's solve for y.
4x+7y=28
Add -4x to both sides.
4x+7y+−4x=28+−4x
7y=−4x+28
Divide both sides by 7.
7y/7=−4x+28/7
y=−4/7x+4
