Answer:
2πr
Step-by-step explanation:
to find the circumference you must multiply the radius by pi and 2
Nine times seven degree (brain list me)
Let s original sides, l length, w width:
s+8=l
s-3=w
lw= 126in²
substitute:
(s+8)(s-3)=126
s²+5s-24=126
s²+5x-150=0
(s-10)(s+15)
s=10
each side is 10 inches
