The perimeter is 16.2. Let me know if you need me to show you how I got this
Answer:
x = 3
Step-by-step explanation:
6x - 4 = 2x + 8
6x - 2x = 8 + 4
4x = 12
x = 12/4
x = 3
Terms: Binomial
Degree: Linear
The answer is 3.75 pounds of water
Answer:
D(V) = 100,48 cm³
Step-by-step explanation:
The volume of a sphere is:
V(s) = 4/3 π*r³
Where r is the radius of the sphere
If we take derivative of V respect r
D(V)/ dr = 4/3*3*π*r² ⇒ D(V)/ dr = 4*π*r² ⇒ D(V) = 4*π*r²*dr
We know:
r = 20 cm and dr = 0,02 ( at most)
Then
D(V) = 4*π*(20)²*0.02 cm³
D(V) = 32*π
D(V) = 100,48 cm³
