Answer:
C = 50.24
A = 7,925.540864 (Round to whatever you want)
Step-by-step explanation:
c = 2πr
c = 2(3.14)(8)
c= 50.24
A = πr^2
A = (3.14)(50.24)^2
A = 7,925.540864

To start you have to write out the possible combinations 7,6,5,4,3,2,1. There are 7 numbers that can be combined in order to find the number of possibilities so 7*6*5*4*3*2*1 = 5,040
Imagine he second side is x so the first side is (x-3) and the third side is (x+4)
So x + (x-3) + (x+4) = 34
3x+1 = 34
3x=33
X=11
So longest side is (x+4) so 11+4=15

To answer this use the Sign Rules
+*+ = +
-*- = +
+* - = -
- * + = -
(-8)(-8)(5)(5)(-8)=
(-8)*(-8) = 64
(64)(5)(5)(-8)
(64)(5) =320
(320)(5)(-8)
(320)(5) = 1600
(1600)(-8) = -12800
so
(-8)(-8)(5)(5)(-8)= -12800
