Your friend is wrapping 1 meter of twine around a spool with a 2-centimeter diameter. The spool is thin and accommodates only one wrap of twine before the twine stacks on top of itself. The twine has a diameter of 1 2 centimeter, which increases the diameter of the spool by 1 centimeter with each wrap. a. Find how many complete times your friend will wrap the twine around the spool. b. Find the percentage of a complete circle that the last wrapping of the twine will make. Round your answer to the nearest tenth.

a) 6 complete times

b) 19.3%

Step-by-step explanation:

In every turn, the diameter of the twine increases 1 cm.

After the first turn, there is a total wrapped of 3.14*2=6.3 cm.

After the second turn, we have wrapped 6.3+3.14*(2+1)=15.7 cm.

If we continue with these algorithm, we have that after the 6th turn we have 84.8 cm wrapped. This is the last complete turn.

T = 0D = 2 cm.Wrapped = 6.3 cm.Total wrapped = 6.3 cm.

T = 1         D = 3 cm.Wrapped = 9.4 cm.Total wrapped = 15.7 cm.

T = 2D = 4 cm.Wrapped = 12.6 cm.Total wrapped = 28.3 cm.

T = 3D = 5 cm.Wrapped = 15.7 cm.Total wrapped = 44 cm.

T = 4D = 6 cm.Wrapped = 18.8 cm.Total wrapped = 62.8 cm.

T = 5D = 7 cm.Wrapped = 22.0 cm.Total wrapped = 84.8 cm.

T = 6D = 8 cm.Wrapped = 25.1 cm.Total wrapped = 110 cm.

There are left (100-84.8) = 15.2 cm to wrap around the twine, which has a 25.1 cm diameter by now.

The perimeter of the twine is 3.14*25.1=78.8 cm.

The percentage of a complete circle that the last wrapping of the twine will make is:

P = 15.2/78.8 = 0.193 = 19.3%

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
