1020 + 1020 = 2040
%60 of 1020 is:612
2040+612=2652
so third one is true
Answer:
ΔV = 0.36π in³
Step-by-step explanation:
Given that:
The radius of a sphere = 3.0
If the measurement is correct within 0.01 inches
i.e the change in the radius Δr = 0.01
The objective is to use differentials to estimate the error in the volume of sphere.
We all know that the volume of a sphere

The differential of V with respect to r is:

dV = 4 πr² dr
which can be re-written as:
ΔV = 4 πr² Δr
ΔV = 4 × π × (3)² × 0.01
ΔV = 0.36π in³
Answer:
C
Step-by-step explanation:
-16 because you need to subtract -4 from -12
Well, ....... X=57/2 or 28.5 but not are equivalent
