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.

The arithmetic mean (average) of four numbers is 85. If the largest of these numbers is 97, find the mean of the remaining three

Margaret [11]

Answer:

Step-by-step explanation:

Let's do this systematically:

Four numbers: a, b, c, d

Whose mean is 85: $\frac{a + b + c + d}{4} = 85$

Whose largest number is 97: $\frac{a + b + c + 97}{4} = 85$

Lets solve for the other numbers:

a+b+c+97 = 85*4 = 340

340 - 97 = 243

a+b+c = 243

at this point it doesn't matter what the numbers are, they just need to add up to 243.

We can do 243÷3=81, which is our answer

Use the net to find the surface area of the cylinder, give your answer in terms of pi.

postnew [5]

Answer:

The correct answer is last option

surface area = 104 yd²

Step-by-step explanation:

Formula:

Surface area of cylinder = 2πr² + 2πrh

Where r is the radius and h is the height of cylinder

To find the surface area of cylinder

Here r = 4 yd and h = 9yd

Surface area = 2πr² + 2πrh = 2π * 4 * 4 + 2π *4 *9

= 32π + 72π = 104π yd²

Therefore the total surface area of given cylinder = 104π yd²

The correct answer is last option .
