Answer:
or
Step-by-step explanation:
step 1
Find the radius of the circular base of the cone
The volume of the cone is equal to
we have
substitute
simplify pi
step 2
Find the volume of the hemisphere
The volume is equal to
we have
----> is the same that the radius of the cone
substitute
step 3
Find the volume of the solid shape
we know that
The volume of the solid shape is equal to the volume of a cone plus the volume of a hemisphere
so
Convert to mixed number
Circumference of a sphere: 2 * pi * r
8 / 2 = 4
r = 4
surface area of a sphere: 4 * pi * r^2
4 * pi * 4^2
4 * pi * 16
64pi
answer is c :)
Answer:
d) Conclude that the population mean annual consumption of beer and cider in Milwaukee is greater than 26.8 gallons and hence higher than throughout the United States.
Step-by-step explanation:
We have a hypothesis test about the true mean consumptionof beer and cider for U.S. 21+ years-old consumers with the following null and alternative hypothesis:
The result of the test is to reject the null hypothesis.
This means that there is evidence to support the claim that beer and cider consumption was higher than the national average in Milwaukee in 2017 .
