Find the volume of a cylinder that has a diameter of 12 in. and a height of 15 in

daser333 [38]

Answer:

<h3> $\sf{ \boxed{ \bold{1697.14}}}$ </h3>

Step-by-step explanation:

Given,

diameter ( d ) = 12 in

height ( h ) = 15 in

finding the radius of a cylinder

Radius is just half of diameter.

Radius ( r ) = 12 / 2 = 6 in

finding the volume of a cylinder having radius of 6 in and height of 15 in

Volume of a cylinder =  $\sf{\pi \: {r}^{2} h}$ 

⇒ $\sf{ \frac{22}{7} \times {6}^{2} \times 15}$

⇒ $\sf{ \frac{22}{7} \times 36 \times 15}$

⇒ $\sf{1697.14} \: in$ 

Hope I helped!

Best regards!!

Dahl Motors / Week

(1) Car Sold 5 6 7 8 9 10 11 12

(2) Probability 5% 9% 14% 24% 18% 14% 11% 5%

(3) (2 x 3 ) 0.25 0.54 0.98 1.92 1.62 1.40 1.21 0.60

(4) Average sales = 0.25 + 0.54 + 0.98 + 1.92 + 1.62 + 1.40 + 1.21+0.60

= 8.52‬ cars/ week

= 8 cars /week

Profit/ Car = $544

Total weekly profit = 544 x 8

= $4,352

Farthington Auto Sales/ Week

(1) Car Sold 5 6 7 8 9 10

(3) (2 x 3 ) 0.40 1.26 2.17 1.92 0.9 0.6

(4) Average sales = 0.40 + 1.26 + 2.17 + 1.92 + 0.90 + 0.60

= 7.25‬ cars/ week

= 7 cars/week

Profit/ Car = $651

Total weekly profit = 651 x 7

= $4,557‬

From the calculations above , Roger will purchase from Farthington Auto Sales
