True or false ,
1 ) The measure of a vertex angle of a pentagon is 108
my answer is true, but teacher mark wrong , can some one help me what vertex angle of a pentagon ?
-------------
The interior vertex angle of a pentagon is 108 degs.
--------------------------
2) If the lengths of all the sides are double, what happens to the volume, justify your answer
my answer is 3 time , but teacher is mark wrong , can some one help me how many time Please !
-----------------
Volume is a function of the cube of the dimensions.
eg, volume of a cube with sides of s is s^3
If you double s, you get (2s)^3 = 8*s^3
---------------
It's 8 times.
