Well first the formula for finding exterior angles is (n-2)180
n is the number of angles, so if u have fifteen sides you do (15-2)180
13 x 180 = 2340
Value=amount times cost per unit
paper=10 times 0.55
pencils=6 times 0.75
she bought 10 paper and 6 pencils
cost=10*0.55+6*0.75=$10.00 total
A=(pi)d
158.368=3.14d
d=50.436
r=25.218
