Answer:
volume of redwood tree is 6400 π ft^3(option 4)
Step-by-step explanation:
concept =
volume of cylinder = πr^2l
where r is the radius and l is the length of cylinder
circumference of cylinder = 2πr
_____________________________________
shape of redwood tree can be taken as cylindrical
given
circumference of a redwood tree trunk is 16π ft
2πr = 16π
=> r = 16π/2π = 8
Thus, radius is 8 feet
Therefore volume of redwood tree = πr^2l = π8^2*100 = π*64*100
volume of redwood tree =6400 π ft^3
31 in total and the smaller one has 13. So just subtract 31-13 and it means there are 18 balls in the larger bag
Answer:
9
Step-by-step explanation:
Plug in -2 for x, and -1 for y, and solve:
3x - 4y + 11
3(-2) - 4(-1) + 11
Remember to follow PEMDAS. First, multiply. Remember, that when you multiply:
2 positive signs will result in a positive answer.
1 positive & 1 negative will result in a negative answer.
2 negative will result in a positive answer.
3 * -2 = -6
-4 * -1 = 4
-6 + 4 + 11 = 9
9 is your answer.

Answer: 35 and 27
Step-by-step explanation:
We can solve this by using a system of equations
x will be the first number while y will be the second
This equation means the two numbers will add to get 62
This equation means when subtracted the two numbers will have the difference of 8.
Now I will solve by elimination
When adding the two equations why was eliminated so now we can find the value of x
Now sub in x into one of the original equations to find the value of y
Answer:
y = 8x + (any number other than 7)
Step-by-step explanation:
All of the other lines will be parallel to y = 8x + 7 they will never cross so there isn't a solution.
