What is the volume of a 9 cm sphere?
The volume of a sphere is equal to 43 times Pi π times the radius cubed. Substitute the value of the radius r=9 into the formula to find the volume of the sphere. Pi π is approximately equal to 3.14 .
How do you find the volume of something in science?
To find the volume of a rectangular object, measure the length, width and height. Multiply the length times the width and multiply the result by the height. The result is the volume. Give the result in cubic units, such as cubic centimeters.
What is volume in science examples?
Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.
What is Sphere and its formula?
The general equation of a sphere is: (x – a)² + (y – b)² + (z – c)² = r², where (a, b, c) represents the center of the sphere, r represents the radius, and x, y, and z are the coordinates of the points on the surface of the sphere.
What is the surface area and volume of a sphere?
A sphere is a perfectly round geometrical 3-dimensional object. It can be characterized as the set of all points located distance r (radius) away from a given point (center). A sphere with radius r has a volume of 4 3 π r 3 \frac{4}{3} \pi r^3 34πr3 and a surface area of 4 π r 2 4 \pi r^2 4πr2. …
What is the volume of a hemisphere?
The volume of the hemisphere is derived by Archimedes. The volume of a hemisphere = (2/3)πr3 cubic units. Where π is a constant whose value is equal to 3.14 approximately. “r” is the radius of the hemisphere.
What is the formula of curved surface area of a sphere?
The formula to find the surface area of sphere is 4 times of pi (π) and radius-squared (r2).
What is 4/3 in the volume of a sphere?
The formula for the volume of a sphere is V = 4/3 πr³. See the formula used in an example where we are given the diameter of the sphere.
What tool is used to measure a sphere?
spherometer
What is the length width and height of a sphere?
Since the distance from that point is the same in all directions, a sphere is like a 3-dimensional extension of a circle. The height, width, and length of a sphere are all equal, and that dimension is called the sphere’s radius.
Does a sphere have a width?
Like a circle, a sphere has a radius and a diameter. The shape of the earth is like a large sphere — it has radius of about 4000 miles. Let’s find the volume of this large sphere, with a radius of 13 feet. Notice that the radius is the only dimension we need in order to calculate the volume of a sphere.
