Okay so the formula to find the circumference of a circe is:
pie times the diameter
or
2 times the radius multiplied by pie
Circle 1: 131.88
Circle 2: 15.7
It can be:
2x2x2x2x7
Or, it can be:
2^3x7
Hope it helped :)
A vertical stretch is the stretching of a line away from the x-axis.
0,2
8-6= 2
2/10= 0.2
0.2 x 10= 2+ 6= 8
