1 Volume:The radius r of a sphere is increasing at a rate of 2 inches per minuteFind the rate of change of the volume when r=6 inches and r=24 inchesExplain why the rate of change of the volume of the sphere is not constant even though dr/dt is constant 2 Volume:The radius r...
The volume of a sphere is found by using the formula 43π r^3 where r is the radius. In this case, the radius is 4 miles, so the volume is (256)3π cubic miles. This is equal to the volume of a cylinder of radius 8 miles so (256)3π=π8^2h, since the volume of a ...
Example 2: Find the volume of a sphere of radius 5 feet. Round your answer to the nearest tenth. Solution: The given radius of the sphere is r=10 ft. \( V=\frac{4}{3} \pi r^3 \) [write the formula for volume] \( =\frac{4}{3} \pi (5)^3 \) [substitute for r] ...
1、surface area and volume of spheres a sphere is the set of all points in space that are the same distance from a point, the center of the sphere. a radius of a sphere is a segment from the center to a point on the sphere. a chord of a sphere is a segment whose endpoints are...
In the three dimensional geometry, a sphere is a shape that maintains a constant distance from a fixed point (center). This constant distance between the center of the sphere and the surface of the sphere is called the radius of the sphere. ...
