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
Answer: Either 28in or 26in
A table cloth 40 inches squared could be 1 by 40, 2 by 20, 4 by 10, 5 by 8
1 by 40 would have a perimeter of 1(2) + 40(2) = 82in
2 by 20 would have a perimeter of 2(2) + 20(2) = 44in
4 by 10 would have a perimeter of 4(2) + 10(2) = 28in
5 by 8 would have a perimeter of 5(2) + 8(2) = 26in
1 by 40, and 2 by 20 are highly unlikely table cloths so it is either 26in or 28in
Answer:
n = 9
Step-by-step explanation:
7n + 5 = 68
7n + 5 - 5 = 68 - 5
7n = 63
7n / 7 = 63 / 7
n = 9
