The standard choice would be the usual representation in spherical coordinates. Let
![x=4\cos\theta\sin\varphi](https://tex.z-dn.net/?f=x%3D4%5Ccos%5Ctheta%5Csin%5Cvarphi)
![y=4\sin\theta\sin\varphi](https://tex.z-dn.net/?f=y%3D4%5Csin%5Ctheta%5Csin%5Cvarphi)
![z=4\cos\varphi](https://tex.z-dn.net/?f=z%3D4%5Ccos%5Cvarphi)
We get the part of the sphere between the planes
with
and
.
Answer:
Your answers are correct except the 7th
7th Answer : 6 + 5a
Step-by-step explanation:
12) 2a - 8 = 14 ⇔ 2a = 22 ⇔ a = 11
13) 2(a + 3)
16) 3x - 1 = 7 ⇔ 3x = 8 ⇔ x = 8/3
Answer:
Surface Area: 615.75
Volume: 1436.76
Step-by-step explanation:
The equation for the surface area of a sphere is 4*pi*r^2
Just do 4*3.14*7*7
The equation for the volume of a sphere is 4/3*pi*r^3
Just do 1.33*3.14*7*7*7
Answer:
7 and 5 down
