Lets get started :)
The Volume formula of a Cylinder is
V =
r²h
(r = radius, h = height)
The radius given is 8 and the height is 4, We can plug in the known values
V =(8)²(4)
=256
= 256 units³ (You can leave the answer in this form)
≈ 804.2 units³ (approximately)
Units³ because it is a volume (3D shape)

It's choice C as the root overhead bar goes over all of (x-7) and not just the x. So you have the correct answer.
f(x) = x^4+7
y = x^4+7
x = y^4+7
y^4 = x-7
y = FourthRoot(x-7)
![y = \sqrt[4]{x-7}](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B4%5D%7Bx-7%7D)
f(x) = x^4+7
y = x^4+7
x = y^4+7
y^4 = x-7
y = FourthRoot(x-7)
