A circle inside of a square. The circle touches all sides of the square. The base is 5 centimeters.
lina2011 [118]

Answer:

19.6 cm²

Step-by-step explanation:

If a circle fits perfectly inside of a square, then its diameter is equal to the length of sides of the square.

The area of a circle is given by:

A= \pi \frac{d^2}{4}

In this problem, d = 5 cm, the area of the circle is:

A= 3.14 *\frac{5^2}{4} \\A=19.6\ cm^2

The approximate area of the circle is 19.6 cm².

What is the converse of the given conditional statement?
Paha777 [63]
The converse of an if statement is a statement in which the hypothesis and conclusion are switched.

<span>You will get into college if you work hard.

The "if" part is the hypothesis.
The "then" part is the conclusion.

Rewrite the original if statement in the if-then form:

If you work hard, then you will get into college.

The hypothesis is the if part: "you work hard"
The conclusion is the then part: "you will get into college"

To write the converse, switch the hypothesis and the conclusion.

If you get into college, then you worked hard.

This happens to be choice A.

Which value is equivalent to: 1 1/2 divided by 4 1/2 x 1 1/3
Nostrana [21]

Answer:

The answer is 4/9

Step-by-step explanation:

Hi. Here's the work.

First turn everything into an improper fraction.

1 \frac{1}{2} ÷ 4 \frac{1}{2} * 1 \frac{1}{3} = \frac{3}{2} ÷ \frac{9}{2} * \frac{4}{3}

To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.

\frac{3}{2} ÷ \frac{9}{2} * \frac{4}{3} = \frac{3}{2} *\frac{2}{9} *\frac{4}{3}

Now we just multiply the fractions!

\frac{3 * 2 * 4}{2 * 9 * 3} = \frac{4}{9}

The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)
