Can someone help me find the area of this circle and round to the nearest tenth

the circle has a diameter of 12, thus its radius is half that, or 6.

$\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=6 \end{cases}\implies A=\pi 6^2\implies A=36\pi \\\\\\ A \approx 113.0973355\implies A=\stackrel{\textit{rounded up}}{113.1}$

OverLord2011 [107]

Answer:

Arithmetic

An = A[n - 1] + 3/5

An = 3/5[n]

Step-by-step explanation:

Number of days = 5

Number of chocolate = 3

Computation:

Recursive:

Number of chocolate eat per day = 3/5

So,

First term a1 = 3/5

So,

An = A[n - 1] + 3/5

Explicit:

An = 3/5 + 3/5[n-1]

An = 3/5[n]

What's the actual value of pie

musickatia [10]

$\text{The exact value of }\pi \text{ can be found by the formula below:} \\ \\ \pi = 4\cdot \Big( 1-\dfrac{1}{3}+\dfrac{1}{5}-\dfrac{1}{7}+\dfrac{1}{9}-\dfrac{1}{11}+\dfrac{1}{13}-...\Big)\\ \\ \text{This series converges to the exact value of }\pi.$
