Find the missing dimension of the cylinder. round your answer to the nearest whole number

Ulleksa [173]

Answer:

11 meters

Step-by-step explanation:

Use the formula:

$V = \pi r^{2} h$

V = 7599, h = 20, π = 3.14

Plugin the numbers and solve for r

$7599=3.14(20)r^{2} \\7599=62.8r^{2} \\7599/62.5=62.8r^{2} /62.8\\121=r^{2} \\\sqrt{121}=\sqrt{r^{2} } \\r=11$

In a different dimension, cows have $x+3$ legs, with 3 toes on each leg. Chickens have $2x-4$ legs, with 7 toes on each leg. If

Juli2301 [7.4K]

Answer:

20x-10

Step-by-step explanation:

Cows have $x+3$ legs and 3 toes on each leg, if we want to find the number of toes of ONE cow we have to multiply the legs by the toes giving the following:

$3(x+3) \quad (1)$

But we have two cows so (1) we have to multiply it by 2 giving a total of:

$2(3(x+3))\\6(x+3)\\6x+18 \quad (2)$

By the other hand chickens have $2x-4$ legs and 7 toes on each leg, if we want to find the number of toes we have to multiply the legs by the toes giving the following:

$7(2x-4)\\14x-28 \quad (3)$

To find the total amount of toes we have to add (2) and (3)

$(6x+18)+(14x-28)\\20x-10$

What is the answer to the equation 5+2(x-1)=12

S_A_V [24]

$5+2(x-1)=12 \\ \\ 2 ( x - 1) = 12 - 5 \ / \ subtract \ 5 \ from \ each \ side \\ \\ 2(x - 1) = 7 \ / \ simplify \\ \\ x - 1 = \frac{7}{2} \ / \ divide \ each \ side \ by \ 2 \\ \\ x = \frac{7}{2} + 1 \ / \ add \ 1 \ to \ each \ side \\ \\ x = \frac{9}{2} \ / \ simplify \\ \\$

So, the answer to this problem is x = 9/2 or x = 4.5.
