Answer:
Here
Step-by-step explanation:
1. Set B: 20, 18, 7
2. 17, 14, 14
2=1.04^t
t=ln2/(ln1.04)
t=17.673 (approx)
so t=18 (although you will have slightly more than double)
Answer:
35cm
Step-by-step explanation:
The net of a regular pentagon has 10 sides.
Since each of the faces are equilateral triangles, the side lengths are equal.
Therefore:
Length of each side of the net = 70/10 =7cm
Therefore, the base is a regular pentagon of side length 7cm.
The perimeter of the base of the pyramid = 5 X 7
=35cm
The perimeter of the base of the pyramid is 35cm.
