Answer #1:Mass is the product of volume and density. You can find the volume of a spherewith a radius of four (regardless of the unit of measure) using v=4/3pi(r3). Withthe volume you must multiply by the density to find the mass.======================================Answer #2:As written, the question has no answer, simply because the mass of a spheredoesn't depend on its size. A hundred spheres can easily all have the same sizebut a hundred different masses.

The answer depends on what the ratio is relative to!The ratio of a circumference to the area of a circle is half the radius.

To find the volume we must first work out what the radius is: 2*pi*radius = 929 Divide both sides by 2*pi to find the value of the radius: radius = 147.8549421 volume = pi*147.85494212*6 volume = 412071.7235 cubic units

Volume=(pi)(radius^2)(height)

Not enough information has been given but the volume of a cone is 1/3*pi*radius squared *height and its base area is pi*radius squared

Not enough information has been given but the volume of a cone is 1/3*pi*radius squared *height and its base area is pi*radius squared

The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.

In a circle, the area of the circle is pi times the radius squared

Use the equation for the volume of a cone, replace the known height and volume, and solve the resulting equation for the radius.

. Find the volume of a cylinder with radius 5 cm and height 7 cm.

to obtain the ratio of surface area to volume, divide the surface area by the volume.

A sphere with a volume of 50 units3 has a radius of 2.29 units. A sphere with twice the radius (4.58 units) has a volume of 402 units3.
