Answer:

12.56 cm

Step-by-step explanation:

Area of a circle is A=3.14 r to the second power.

so the radius is 2 cm. I would do 2 x 2 and that equals ,4 next 4 x 3.14= 12.56

i don't know what pie=3 means but this is my answer from the best of my ability.

Answer:

12

Step-by-step explanation:

The formula to find the area of a circle is:

\pir^{2}

Where "r" is the radius of the circle.

In this case, the radius is 2, and as per what is given in this problem (what the problem asks one to use), pi is rounded down to 3.

The equation will be:

3 * 2^2

Simplify, remember the order of operations:

3 * 4

A little help? A set of numbers is given below. √72, 9.25, √83, 2, 8.7 Which list correctly orders the numbers from least to gre
Burka [1]

Answer:

2, √72, 8.7, √83, 9.25

Step-by-step explanation:

First, you need to find the integers of each number that is not already a integer.

Square root of 72: 8.48528137424

9.25

Square root of 83: 9.11043357914

2

8.7

Now, list the numbers by their whole number (in the ones place). If they have the same whole number, look at their tenths place and see which one is greater.

Overall, the answer would be 2, √72, 8.7, √83, 9.25.

Find the domain of h(x)= 1/ 3x^2-15x
Schach [20]

Hello!

To find the domain of the function h(x), we need to find the values of x where it is undefined.

We can begin by factoring the denominator of the rational function, h(x).

h(x) = 1/(3x² - 15x) (factor 3x from the binomial)

h(x) = 1/3x(x - 5)

After factoring the denominator, apply the zero product property.

3x = 0 (divide both sides by 3)

x = 0

x - 5 = 0 (add 5 to both sides)

x = 5

The values of 0 and 5 cause h(x) to be undefined. The function h(x) comes from negative infinity to zero, where there is an asymptote. Also, from zero to five, there is also an asymptote. Finally, the function h(x) also goes to infinity from five.  

So therefore, the domain of the function h(x) is: (-∞, 0) ∪ (0, 5) ∪ (5, ∞).
