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
Answer:
-1/5
Step-by-step explanation:
slope can be found with the equation found in the image.
assign each coordinate with the according variable
x1 = 3 x2 = -7 y1 = 2 y2 = 4
and input the values accordingly.
4 - 2 / -7 - 3 PEMDAS (order of operations)
= 2/ -10 Simplify
= 1/ -5
=-1/5
Answer: 30 m
Workinh Out: 20 divided by 0.8 = 25.
1.2 x 25 = 30
