Answer:
Z = 8.41
Step-by-step explanation:
Given that standard deviation = 72
Mean = 60
Z = marginal error
Z = 72/√60
Z = 72/7.746
Z = (9.036)(0.9312)
maybe 1,5
Use the Pythagorean theorem:
We have:
Substitute and solve for x:
7.07
B. V=SA
The volume is 113.1 and the surface area is also 113.1 so Volume is equal to the Surface Area
