Suppose a cylinder has a diameter of 18 feet and a height of h feet. Which equation can be used to find V, the volume of the cyl

IrinaVladis [17]

Answer: option A

Step-by-step explanation:

The volume of a cylinder can be calculated with the formula:

$V=\pi r^2h$

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

The radius is diameter divided by 2, then:

$r=\frac{18ft}{2}\\\\r=9ft$

Substitute the radius into the formula. Then you get the following equation that can be used to find V, the volume of the cylinder:

$V=\pi (9)^2h$

Your family goes to a restaurant for dinner. There are 7 people in your family. Some order the chiken dinner for $ 12 dollars an

aleksandrvk [35]

Answer:

The number of people who ordered steak dinner is 5

The number of people who ordered chicken dinner is 2

Step-by-step explanation:

Given as :

The total number of people went for the dinner = 7

The total bill price for the dinner = $ 109

The price for the chicken dinner = $ 12

The price for the steak dinner = $ 17

Let The number of people who ordered chicken dinner = c

And The number of people who ordered steak dinner = s

Now, According to question

The total number of people went for the dinner = The number of people who ordered chicken dinner + The number of people who ordered steak dinner

Or, c + s = 7

And The total bill price for the dinner = The price for the chicken dinner × The number of people who ordered chicken dinner + The price for the steak dinner × The number of people who ordered steak dinner

Or, $ 12 × c + $ 17 × s = $ 109

Now, solving the equations

$ 12 × ( c + s ) = $ 12 × 7

Or, $ 12 × c + $ 12 × s = $ 84

Or, ( $ 12 × c + $ 17 × s ) - ( $ 12 × c + $ 12 × s ) = $ 109 - $ 84

Or , ( $ 12 × c - $ 12 × c ) + ( $ 17 × s - $ 12 × s ) = $ 25

Or, ( 0 ) + ( $ 5 s ) = $ 25

∴ s = $\frac{25}{5}$

I.e s = 5

So, The number of people who ordered steak dinner = s = 5

Put the value og s in Eq A

∵, c + s = 7

or, c = 7 - s

Or, c = 7 - 5

I.e c = 2

So , The number of people who ordered chicken dinner = c = 2

Hence The number of people who ordered steak dinner is 5

And The number of people who ordered chicken dinner is 2 Answer

. Tina walked 20 miles for a fundraiser. Lia

Leno4ka [110]

Answer:

The relation for the distance cover by Tina and Lia is 20 = 4 × m

Option B

Step-by-step explanation

Given as :

The distance cover by Tina = $D_1$ = 20 miles

The distance cover by Lia = $D_2$ = m miles

According to question

Tina walked 4 times as far as Lia

So, The distance cover by Tina = 4 × The distance cover by Lia

Or, $D_1$ = 4 × $D_2$

I.e 20 miles = 4 × m miles

or. 20 = 4 × m

So, relation is 20 = 4 × m

Hence, The relation for the distance cover by Tina and Lia is 20 = 4 × m
