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

DochEvi [55]
First of all f(2)=2(2)-5=-1 and f(5)=2(5)-5=5
so
f(2)+f(3)=-1+5=4

Simora [160]

Answer:

1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}

Step-by-step explanation:

Taking the succession:

1+r+r^{2}+r^{3}+.....+r^{n-1}

You can multiply and divide by 1-r without chaging the result:

\frac{1-r}{1-r} (1+r+r^{2}+r^{3}+.....+r^{n-1})

Distributing the upper part of the fraction you have:

\frac{1}{1-r} (1-r+r-r^{2}+r^{2}-r^{3}+r^{3}-r^{4}+.....+r^{n-1}-r^{n})

As can be seen all the intermediate members will be canceled by a same member with opposite sign, only (1-r^{n}) will be left so:

1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}
