Jodie has chosen a set of vases for her wedding registry. The vases are cylindrical and their dimensions (in inches) are as follows. • Vase A: h = 12 and r= 2
• Vase B: h = 6 and r = 4
Which of the following statements about the volumes of the vases is true?
OA. The volume of vase A is half the volume of vase B.

ОВ. The volumes of the two vases are equal.

OC. The volume of vase B is half the volume of vase A.

OD. The volume of vase B is four times the volume of vase A.

Option A

Step-by-step explanation:

V = πr2h = π·22·12 ≈ 150.79645 - Vase A

V = πr2h = π·42·6 ≈ 301.59289 - Vase B

the perimeter is increased by a factor of 2

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.
