Answer:

<h2>Use the formula A = π(r²)   where r is the radius</h2>

Step-by-step explanation:

π = pi, and r is the radius.   It's the only value you need to find the area of a circle.  π is usually represented as 3.14, or you can use the π button on your calculator

How do you graph 193 + y is greater than or equal to 201
Travka [436]

Answer:

The correct answer is y ≥ 8

Step-by-step explanation:

In order to graph this, we must first solve the equation for y.

193 + y ≥ 201

y ≥ 8

Now that we have the solved version, we can graph on a number line. Draw a closed circle on the point 8 and then draw an arrow to the right to show that it is greater.

Which of the numbers below are whole numbers A 0.328 B.678.79 C.159113 D.3809 E.757 F.0​
Naily [24]

Answer:

F

Step-by-step explanation:

F

zero

Anytime you have zero as a possible answer, you have to consider it carefully. Part of the whole number system is 0. They go up from there. No fraction is a whole number. No decimal is a whole number except those that are equal to  a whole number.

The rest are all decimals so they are not whole numbers. Note I just noticed that the other numbers have periods after the choice. There are other whole numbers there if that is the case.

C D E and F are all whole numbers if that is a period after their choice letters.
