A sphere has a radius of 12 inches. A second sphere has a radius of 9 inches. What is the difference of the volumes of the spheres? The volume of the larger sphere is π cubic inches greater than the volume of the smaller sphere.

The volume of a sphere is 4/3 x π x (diameter / 2) 3 , where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4/3 x π x radius 3.

Step-by-step explanation:

The volume of the cone is equal to 18π cubic units. What is the radius of the cone? The diameter of a sphere is 4 centimeters. Which represents the volume of the sphere? A gardener uses a tray of 6 conical pots to plant seeds. Each conical pot has a radius of 3 centimeters and a depth of 8 centimeters.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
