Answer:
A.
Step-by-step explanation:
C = 2πr = πd
A. C = π(38.5 in.) = 120.95 in.
First guess: Answer: A.
a2+b2=c2
a=x
b=24
c=26
a2+24 squared=26 squared
a2+576=676
-576 -576
a2=100
Then, square root both sides.
It should be a/x=10
The answer is the square root of 4.
2 * 2 = 4
2 is a rational number; therefore, the square root of 4 is a rational number.
2 2/3 = [(2*3)+2]/3 =8/3
(8/3)/5=8/(3*5)=8/15
