P = [60] cm
Explanation:
6.5 cm + 6.5 cm + 7.5 cm + 7.5 cm + 7.5 cm + 7.5 cm + 8.5 cm + 8.5 cm
There are no numbers without decimals which multiply to 78 and add up to 17.
Answer:
C = 2πr = 16.3
2(3.14)r = 16.3
r = 16.3/6.28
r = 2.5955414
Area: A = πr2
A = 3.14(2.5955414)2
A = 21.15366242 
Step-by-step explanation:
The answer would be 21.2 
Answer:
a=-3
b=6
Step-by-step explanation:
equation 1: ax+6
equation 2: -3x+b
get the -3 from equation 2 and plug it into equation 1
get the 6 from equation 1 and plug it into equation 2
