Answer:60.8

Step-by-step explanation: Just do 12/2 and 8/2 and plug those numbers into the area of a circle formula that is A=πr2 and subtract those numbers

Answer:

62.8

Step-by-step explanation:

To find the area of metal required, we calculate the area of the outer circle and subtract the area of the two inner semicircles. The area of the outer circle is,

AOC=πr2=π(62)=113.0973 in2

The area of the inner semicircles is,

AIC=2⋅12πr2=π(42)=50.26548 in2

The total area of the sign is,

A=113.0973−50.26548=62.83182 in2

Rounded to one decimal place, the area of metal required is 62.8 square inches.

Find the GCF of 207c^3 and 108c^2
geniusboy [140]

Answer:  9c²

<u>Step-by-step explanation:</u>

To find the Greatest Common Factor of 207c³ and 108c², first factor them down to their primes and see what they have in common.

                207c³                     108c²

                 ∧   ∧                        ∧  ∧

             9·23  c·c·c              9·12   c·c

            ∧                            ∧  ∧

           3·3                         3·3 3·4

                                                  ∧

                                                 2·2

                   

207c³: 3·3·23  c·c·c

108c²:  2·2·3·3·3·4 c·c

GCF = 3·3 c·c

        = 9c²

Determine whether the sequence converges or diverges. if it converges, find the limit. (if an answer does not exist, enter dne.
Arada [10]

The sequence a_n=\frac{n^2}{n^3+5n} diverges.

For given question,

We have been given a sequence a_n=\frac{n^2}{n^3+5n}

We need to determine whether the sequence converges or diverges.

From given sequence we have, a_{n+1}=\frac{(n+1)^2}{(n+1)^3+5(n+1)}

We use Ratio Test.

According to Ratio Test, r=\frac{a_{n+1}}{a_n}, where sequence converges if and only if |r| < 1.

Consider,

\lim_{n \to \infty} |\frac{a_{n+1}}{a_n} |\\\\= \lim_{n \to \infty} |\frac{\frac{(n+1)^2}{(n+1)^3+5(n+1)}}{\frac{n^2}{n^3+5n}} |\\\\\\= \lim_{n \to \infty} |\frac{(n+1)^2(n^3+5n)}{n^2[(n+1)^3+5(n+1)]} |\\\\=\infty

Since \lim_{n \to \infty} |\frac{a_{n+1}}{a_n} | is not defined, the sequence a_n=\frac{n^2}{n^3+5n} diverges.

Therefore, the sequence a_n=\frac{n^2}{n^3+5n} diverges.
