Read this how-to lesson to learn what steps you need to take to find the volume for a sphere with a radius of 4. Learn what the formula is and how to use it. The Steps In this lesson, you'll learn how to find the volume of a sphere with a radius of 4 inches. A ...
A sphere is a three-dimensional, round object, such as a marble or soccer ball. The volume represents the space enclosed by the object. The formula for the volume of a sphere is 4/3 times pi times the radius cubed. Cubing a number means multiplying it by itself three times, in this ...
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] ...
Find the square of the radius by multiplying it by itself. Step 5 Multiply the result in Step 4 by 4π (4π is equal to approximately 12.56). The answer is equal to the surface area of the sphere. References Think Central: The Volume of a Sphere Math.com: Surface Area Formulas Cite ...
To determine the volume of the hollow sphere, we need to subtract the volume of the hollow region from the volume of the entire sphere with radius r and R respectively. To find the volume of a solid sphere we use the formula 4/3π r3. And to find the volume of the hollow sphere we...
Answer to: Show how to find the surface area of a sphere with a radius of 8 cm. By signing up, you'll get thousands of step-by-step solutions to...
Volume versus circumradiusis based on a quotient of the element volume and the radius of the circumscribed sphere (or circle) of the element. This quality measure is sensitive to large angles, small angles, and anisotropy. For triangular meshes in 2D and tetrahedral meshes in 3D where isotropic...
Density (ρ) is defined as mass (m) per unit volume (V): ρ =m/V. To calculate the density of a sphere, determine its mass, then measure its radius and use the expression (4/3)πr^3 to find its volume. In practice, it's usually easier to measure diameter
Satellites do not give off information about angles, so the location of a GPS device could be anywhere on a sphere’s surface area. When a satellite sends a signal, it creates a circle with a radius measured from the GPS device to the satellite. When we add a second satellite, it ...
4π/3 to find the volume of a sphere. For example, if the radius of the sphere is 2 cm, then 2 raised to the third power, or 2 multiplied by 2 multiplied by 2, equals 8 cubic centimeters. Eight multiplied by 4π/3 equals 33.5. The volume of the sphere is 33.5 cubic centimeters...
