The equation above can be used to calculate the volume V, of a sphere with radius r. If the volume of a sphere is 288πcm3, what is the radius of the sphere in centimeters? Select one: A. 13 B. 9 C. 16 D. 6

Step-by-step explanation:

V=4/3πr^3

288πcm^3=4/3×π×r^3

288π×3cm^3=4πr^3

864π=4πr^3

r^3=216

r=6cm

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
