Answer:

100π and $\frac{500\pi }{3}$

Step-by-step explanation:

<em>The other picture wouldn’t attach, but the radius is 5.</em>

Surface area = 4πr²

r= 5

4.π5²= 25.4.π = 100π

<em>Volume =</em> $\frac{4}{3} \pi r^{3}$

r=5

$\frac{4}{3} \pi 5^{3} = 125.4.\pi$ = $\frac{500\pi }{3}$

Hope this helps ^-^

Graph the following piecewise function.

atroni [7]

Answer:

The graph of this piece-wise function is attached below.

Step-by-step explanation:

Given the function

${\displaystyle f(x)={\begin{cases}x^{2} +2&{\text{if }}-5\leq x$

A piece-wise function is a function which has multiple pieces.
Each of the pieces have their own restrictions.

The domain of a function is the set of input, or x, values for which the function is defined.
The range is the set of all values taken by the function

As the piece

$f(x)=x^{2} +2$ has the domain [-5, 3) and graph of this piece is attached below.

and

$f(x)=x-4$ has the domain [3, 7) and graph of this piece is attached below.

So, the domain of the piece-wise function can be composed as [-5, 3) U [3, 7) and range has the interval $\:\left[-1,\:27\right]$ .

i.e.

Domain: [-5, 3) U [3, 7)

Range: $\:\left[-1,\:27\right]$

The graph of this piece-wise function is attached below.

➷ The formula to calculate the circumference is $\pi d$

d is the diameter (double the radius)

Substitute the values in:

Circumference = (3.14)(3 x 2)

Circumference = 18.84

It would be option D. 18.84 m

➶ Hope This Helps You!

➶ Good Luck (:
