Answer:
V(hemisphere) = 1072.3in^3
Step-by-step explanation:
To find the volume of a hemisphere, we will have to take the volume of a sphere as a whole and divide it by 2. This is because a hemisphere is half of a sphere.
The volume of a sphere is:

Let's plug in the radium of 8 into the equation and solve:

Now, divide it by 2
V(sphere) = (2144.660585)/2
V(hemisphere) = 1072.3in^3

Answer:4.21,4.22,4.23, 4.24
Step-by-step explanation:
4 1/5 is 4.2 as a decimal and the numbers between 4.2 and 4.5 as numbers with 2 places past the decimal place are the ones above.
Answer:
5.
4 + 2(-7 - (5 - 15))
= 4 + 2(-7 - (-10))
= 4 + 2(-7 + 10)
= 4 + 2(3)
= 4 + 6
= 10
6.
((6 - 5)^8 - 1)/(-5(-2) - 4)
= (1^8 - 1)/(10 - 4)
= (1 - 1)/6
= 0/6
= 0
7.
(14² - 8²)/(-3(8 - 3²))
= (196 - 64)/(-3(8 - 9))
= (196 - 64)/(-24 + 27)
= 132/3
= 44
