Se cocina una pizza de 20 cm de radio, en su interior se coloca al azar 12 piezas de salami

Furkat [3]

Answer:

The area of cheese is 388π cm.

Step-by-step explanation:

Given that,

Radius of pizza = 20 cm

Number of pieces = 12

Radius of circle = 1 cm

We need to calculate the area of pizza

Using formula of area

$A=\pi\times r^2$

Put the value into the formula

$A=\pi\times20^2$

$A=400\pi\ cm^2$

We need to calculate the area of circle

Using formula of area

$A'=\pi\times r^2$

Put the value into the formula

$A'=\pi\times1^2$

$A'=\pi\ cm^2$

Now, we multiply the result by 12 because they are 12 salamis.

So. the area of salamis will be

$A'=12\pi\ cm^2$

We need to calculate the area of cheese

The total area of the pizza and subtract the area of the salamis

$A''=A-A'$

Put the value in to the formula

$A''=400\pi-12\pi$

$A=388\pi\ cm^2$

Hence, The area of cheese is 388π cm.

If y=mx+b,

$\frac { dy }{ dx } =m$

You can't differentiate a constant, so dy/dx=m.

rewona [7]

Answer:

The answer is 175.5.

Step-by-step explanation:

This is because 25% of $260 is $65. Then you must subtract that from the original price. $260 - $65 = $195. Then, it says '10% off the sale price'. The sale price is $195. 10% of this is 19.5. Finally, you subtract this from the $195, with a final amount of $175.50
