Answer:

3.14 cm squared

Step-by-step explanation:

First, identify the formula necessary to calculate the area of the circle.

Area of a circle = pi x r^2

Remember, the radius is just half of the diameter! Then to square a number, is to multiply it by itself once.

pi x 1^2 =?

pi x 1

Pi

The circumference of your circle is approximately 3.14 cm squared.

Simplify: ( y^−7 × y^−3 )−1 A. y−21 B. y 21 C. y−10 D. y 10
Firlakuza [10]

Answer:

D

Step-by-step explanation:

The rules we need to simplify this are:

a^x*a^y=a^{x+y}

and

(a^x)^y=a^{xy}

Now, let's simplify the problem:

(y^{-7}*y^{-3})^{-1}\\(y^{-10})^{-1}\\y^{10}

Answer choice D is y^10, so that's correct.

Is 3.80012569923.... a irrational or rational ?
BlackZzzverrR [31]

We can't tell from the information you've given.

With the dots at the end, you showed that there's more
to the decimal.  But you didn't say how much more.

-- If the decimal EVER ends, even after a billion places,
then it's rational.

-- If it repeats, then it's rational.  That .80012569923 may repeat,
or part of it, like the 9923, may repeat, or the whole thing may be
part of some larger bunch that repeats.  We don't know.

A student is given this proof.
Alenkasestr [34]

From the steps below, it has been proved that  by transitive property of congruence, we can say that; ∠CON ≅ ∠BOM

<h3>How to prove congruent angles?</h3>

We are given;

∠AOM ≅ ∠DON

To prove that;

∠CON ≅ ∠BOM

Now, from the image attached, we can say that;

∠BOM ≅ ∠DON because of vertical angles theorem

Similarly, we can say that ∠AOM ≅ ∠BOM due to transitive property of congruence.

Also, we can say that from vertical angles theorem, ∠AOM ≅ ∠CON

Finally, since  ∠AOM ≅ ∠BOM, then by transitive property of congruence, we can say that;∠CON ≅ ∠BOM
