The volume of a sphere is a function of its radius, v=4/3 πr^3 evaluate the function for the volume of a volleyball with radius 11.1 cm.

The volume of a volleyball with radius 11.1 cm is 5731.025 cubic centimeter

Given that volume of a sphere is a function of its radius

Radius = 11.1 cm

To find: volume of a volleyball

Since volleyball is generally of spherical shape, we can use volume of sphere formula

Where "r" is the radius of sphere and is a constant which has value 3.14

Substituting the given radius r = 11.1 cm

volume of sphere = 5731.025 cubic centimeter

Thus the volume of volleyball is 5731.025 cubic centimeter

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

step-by-step explanation:

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
