Find the surface area of each figure. Round your answers to the nearest hundredth, if necessary

396π.cm^3

Step-by-step explanation:

ere's your solution

=> height of cylinder = 11 cm

=> radius of cylinder = 6 cm

=> volume = πr^2h

=> putting the value of radius and height in formula

=>volume = 6^2*11 π

=> volume = 36*11 π

=> Volume = 396π .cm^3

the solution is h=10 because you add 9 to each side of the equation.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
