You are choosing between two mugs. One has a base that is 5.5 inches in diameter and a height of 3 inches. The other has a base
professor190 [17]

We should choose mug 1 having volume of  71.24 inch³ ,with diameter 5.5 inches and height 3 inches holds the most !

<u>Step-by-step explanation:</u>

We have 2 mugs, One has a base that is 5.5 inches in diameter and a height of 3 inches. The other has a base of 4.5 inches in diameter and a height of 4 inches. Basically, mugs are cylinders so we will consider 2 cylinders .

To find which one holds the most we are supposed to find volume of both ,the one with maximum volume holds the most.

<u>Part 1: </u>

volume of cylinder 1 (V_{1})= πr₁²h₁ ,

r₁ = radius of cylinder ⇒ \frac{\text {diameter}}{2}=\frac{5.5}{2}=2.75 \text { inches }

h₁ = height of cylinder ⇒  3 inches

∴ V_{1} = πr₁²h₁

⇒ 3.14×( 2.75 )²×3 ⇒ 71.24 inch³

<u>Part 2:</u>

volume of cylinder 2 ( V_{2} )= πr₂²h₂

r₂ = radius of cylinder ⇒ \frac{\text {diameter}}{2}=\frac{4.5}{2}=2.25 \text { inches }

h₂ = height of cylinder ⇒  4 inches

∴ V_{2} = πr₂²h₂

⇒ 3.14×( 2.25 )²×4 ⇒ 63.59 inch³

∵ V_{1} ( 71.24 inch³ ) > V_{2} ( 63.59 inch³ ), mug 1 with diameter 5.5 inches and height 3 inches holds the most.

Vicky drew a scale drawing of a city. She used the scale 1 inch : 2 yards. If the actual width of a neighborhood park is 62 yard
klemol [59]

Answer:

The park is <u>31 inches</u> wide in the drawing.

Step-by-step explanation:

Given:

Vicky drew a scale drawing of a city. She used the scale 1 inch : 2 yards.

The actual width of a neighborhood park is 62 yards.

Now, to find the width of park in drawing.

Let the width of park in drawing be x.

The scale drawing of the city is 1 inch : 2 yards.

So, 1 inch is equivalent to 2 yards.

Thus, x is equivalent to 62 yards.

Now, to get the width of park in drawing by using cross multiplication method:

\frac{1}{2} =\frac{x}{62}

By cross multiplying we get:

62=2x

Dividing both sides by 2 we get:

31=x

x=31\ inches.

Therefore, the park is 31 inches wide in the drawing.

Sati [7]
Hello.

The minimum number of rigid transformations required to show that polygon ABCDE is congruent to polygon FGHIJ is 2 (translation and rotation). 

A rotation translation must be used to make the two polygons coincide. 

A sequence of transformations of polygon ABCDE such that ABCDE does not coincide with polygon FGHIJ is a translation 2 units down and a 90° counterclockwise rotation about point D
