to the nearest tenth cm^3 what is the volume of a sphere with a length of 2.40 cm a width of 2.40 cm and a height of 2.40 cm

Hi :)

The volume of a sphere is

V = 4/3 (pi) r^3

Supposing "length" as diameter

We can take the radius

2.40/2

1.2 is the radius of the sphere.

Inserting the radius into the formula

V = 4/3 (pi) 1.2^3

The volume is aproximately 7.24cm^3

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.
