Multiply 2y by 4y because they are similar
8y=8
8/8=1
Answer:
73.5
Step-by-step explanation:
circumference = 2πr , where r = radius
given radius = 11.7 so r = 11.7
C = 2πr
==> plug in r = 11.7
C = 2π(11.7)
==> multiply 2 and 11.7
C = 23.4π
==> multipl 23.4 and π
C = 73.5 ( rounded to the nearest tenth )
3/4x - 16 = 28
+16 +16
3/4x = 44
*3/4 *3/4
x = 176/3
