The circumference of a circle is 2(3.14)r, and if 8.5 * 2 is 17, the answer will be 17*3.14.

An estimate is 51, and the actual answer is 53.38.

Answer:

C = 53.38 m

Step-by-step explanation:

The formula for circumference is

C = 2 * pi *r

we know the radius is 8.5 and we can approximate pi by 3.14

C = 2 * (3.14) * 8.5

C = 53.38 m

What is the domain for each function below? Choose the correct inequality symbol from the drop down menu and fill in the blank w

erik [133]

Answer:

$x \le 3$

$x \ge 0$

Step-by-step explanation:

The functions, missing from the question are:

$f(x) = \sqrt{3 - x$

$f(x) = \sqrt{3 x$

Required

Determine the domain

To get the domain, means we want to get the possible values of x.

(a)

$f(x) = \sqrt{3 - x$

Equate 3 - x to 0

$3 - x = 0$

Solve for x

$-x = -3$

$x = 3$

From the calculated value of x above;

When x exceeds 3; f(x) = undefined

So: the domain is:

$x \le 3$

(b)

$f(x) = \sqrt{3x$

Equate 3x to 0

$3x = 0$

Solve for x

$x = 0$

From the calculated value of x above;

When x falls below 0; f(x) = undefined

So: the domain is:

$x \ge 0$

Diana is painting statues. She has 7/8 fraction of a gallon of paint remaining. Each statue requires 1/6 of a gallon of paint. h

fomenos

She can paint almost 7 statues - 6.86 statues.

7/8 ÷ 1/6

21/24 ÷ 4/24

21/24 * 24/4 = 576/84

576 / 84 is approximately 6.86.
