Answer:

-14.25 degrees Fahrenheit was the temperature after 10 hours.

Step-by-step explanation:

The temperature before sunrise = -11°F

Temperature after rise by 1/2 degree  each hour for 7 hours that id before dropping.

T=(-11 + \frac{1}{2}\times 7)^oF=-7.5^oF

Now after 7 hours drop in temperature takes place 2\frac{1}{4} degrees each hour for 3 hours, sat T'

T'=(-7.5-2\frac{1}{4}\times 3)^oF

T'=(-7.5-\frac{9}{4}\times 3)^oF=-14.25^oF

-14.25 degrees Fahrenheit was the temperature after 10 hours.

First mug holds the most

<em><u>Solution:</u></em>

Given that,

You are choosing between two mugs

<em><u>The volume of cylinder is given as:</u></em>

V = \pi r^2h

Where,

r is the radius and h is the height

<em><u>One has a base that is 5.5 inches in diameter and a height of 3 inches</u></em>

radius = \frac{diameter}{2}

Therefore,

r = \frac{5.5}{2}\\\\r = 2.75

Also, h = 3 inches

<em><u>Thus volume of cylinder is given as:</u></em>

V = \pi \times 2.75^2 \times 3\\\\V = 3.14 \times 22.6875\\\\V = 71.23875 \approx 71.24

Thus first mug holds 71.24 cubic inches

<em><u>The other has a base of 4.5 inches in diameter and a height of 4 inches</u></em>

Radius = \frac{4.5}{2}\\\\r = 2.25

h = 4 inches

Therefore,

V = 3.14 \times 2.25^2 \times 4\\\\V = 3.14 \times 20.25\\\\V = 63.585

Thus the second mug holds 63.585 cubic inches

On comparing, volume of both mugs,

Volume of first mug > volume of second mug

First mug holds the most

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.
