Izracunaj opseg i povrsinu kruga upisanog u kvadrat stranice duljine 8 cm.

Nutka1998 [239]

(In English), your question would state the following:

Calculate the circumference and circumference of the circle entered in a square 8 cm long.

So when finding the answer this this question, we know that the circumference would be the complete area of a circle.

So, I believe we would want to find what is the radius and the diameter that would make this circumference 8 $^c^m$ .

The radius would then be (1.274).
__________________________________________________________

Now in your own language (Croatian).

Dakle, kad pronađemo odgovor na ovo pitanje, znamo da bi opseg bio cjelokupno područje kruga. Dakle, vjerujem da bismo željeli otkriti što je radijus i promjer koji bi ovaj opseg mogao učiniti 8cm. Radijus bi onda bio (1.274).

How do you turn fractions into decimals?

Anvisha [2.4K]

Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s.

Step 2: Multiply both top and bottom by that number.

Step 3. Then write down just the top number, putting the decimal point in the correct spot (one space from the right hand side for every zero in the bottom number)
