Feliz [49]

Answer:

72.22 inches

Step-by-step explanation:

Okay so the formula for circumference is C=2πr so since the diameter is twice the radius, the radius is 11.5. Now you have to multiply 11.5 and 2. That equals 23. Now you have to multiply 23 by π which is about 3.14. 23 times 3.14 is 72.22 inches.

Hope this helped!! :D

What is the 4th term in the sequence b(n)=1(-2)^n-1
mel-nik [20]
b(n)=1(-2)^n-1

When n = 4, 
b(4)=1(-2)^4-1

b(4)=16-1

b(4)=15

-------------------------------------------------------------

b(n)=1(-2)^{n-1}

When n = 4
b(4)=1(-2)^{4-1}

b(4)=1(-2)^3

b(4)=1(-8)

b(4)=-8
