Answer:

\dfrac{c}{28}=\pi

Step-by-step explanation:

The circumference c of circle of radius r is given by

c=2\pi r,

and the diameter d is 2 times the radius:

d=2r.

Therefore, the ratio of the circumference to the diameters is

\dfrac{c}{d}=\dfrac{2\pi r}{2r}

\dfrac{c}{d}=\pi.

Putting in d= 2r =28, we get

\boxed{ \dfrac{c}{28}=\pi}

B(n) = -1 (2)^n-1 What is the 5th term in the sequence?
bija089 [108]

Answer:

<h2>The answer is - 16</h2>

Step-by-step explanation:

<h3>b(n) =  - 1 ({2})^{n - 1}</h3>

where

n is the number of terms

From the question since we are finding the 5th term

n = 5

Substitute the value into the above formula and solve

We have

b(5) =  -  1({2})^{5 - 1}  \\  =  - 2 ^{4}

We have the final answer as

<h3>- 16</h3>

Hope this helps you
