For this case we must find the perimeter of the circular carpet.

By definition, the perimeter of a circle is given by:

P = 2 \pi * r

Where:

r: It is the radius of the circle

According to the statement we have:

r = 5 \ ft

Substituting:

P = 2 * 3.14 * 5\\P = 2 * 3.14 * 5\\P = 31.4 \ ft

So, you need31.4 \ ft

Answer:

31.4 \ ft

The length around the rug is the circumference.

The formula is C = 2 x PI x r

C = 2 x 3.14 x 5 = 31.4 feet

Answer:

51 cm^2

Step-by-step explanation:

To find the area excluding the shaded triangle, first find the area of the whole figure:

12 x 6 = 72cm^2

Now, find the area of the triangle:

(7 x 6) / 2

42/2

21cm^2

Lastly, subtract the shaded area from the whole:

72 - 21 = 51 cm^2

There below! Can somebody help me please?
Montano1993 [528]

Answer: C. 24 units

Step-by-step explanation:

The circumference of a circle is 2πr.  Let's say x = 1/3r.  Thus, the area of circle A relative to circle B is 1:3.  Thus, circle B is 3 times larger than circle A.  So, simply divide 64π by 4 to get 16π.  Then multiply 16π*3=48π.  For the circumference of a circle to be 48, the radius would have to be 24.

Hope it helps <3

Evaluate the Riemann sum for (x) = x3 − 6x, for 0 ≤ x ≤ 3 with six subintervals, taking the sample points, xi, to be the right e
DENIUS [597]
Hello,

Reminders:
$\sum_{i=1}^{n} i= \dfrac{n(n+1)}{2}$&#10;&#10;&#10;
$ \sum_{i=1}^{n} i^2= \dfrac{n(n+1)}{2}$&#10;&#10;
$ \sum_{i=1}^{n} i^3= \dfrac{n^2(n+1)^2}{4} $&#10;

n=6\\&#10;x_{0}=0\\&#10;x_{n}=3\\&#10;\Delta= \dfrac{x_n-x_0}{n}=0.5\\&#10;&#10;
x_{i} =0+\Delta*i= \frac{i}{2}

$ \sum_{i=1}^{n}\ \Delta*f(x_{i})=\sum_{i=1}^{6}\  \dfrac{i^3/8-6i}{2} $
$= \dfrac{1}{2}\sum_{i=1}^{6}  (\frac{i^3}{8} -6i)=\dfrac{1}{16}*\frac{(6*7)^2}{4}- \frac{9*7}{2}= -3.9575
