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.
Does circle have volume?
No, a circle doesn’t have a volume. A circle is a two-dimensional shape, it does not have volume. A circle only has an area and perimeter/circumference.
What are equations of circles?
The general equation of a circle is (x – h)2 + (y – k)2 = r2, where (h, k) represents the location of the circle’s center, and r represents the length of its radius.
How do you find the volume of a tube?
The volume of any tube is V = hA, where V is the volume, h is its height and A is the area of a cross-section. Therefore, we have V = Ah = (pi)(r^2)h. Find the volume of a specific cylinder. The volume of a cylinder with radius 3 and height 4 is V = (pi)(r^2)h = (pi)(3^2)(4) = (pi)(9)(4) = 36 (pi).
Does a baseball have volume?
According to The Physics Factbook online, the standard diameter for a baseball is about 7.3 centimeters. The radius would be 3.65 centimeters. Cube the radius (3.65 times 3.65 times 3.65) to get 48.627. Multiply 4.1762 times 48.627 to get a volume of 203.076 cubic centimeters.
Why is the formula for area of a circle?
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
How do you find the volume of a sphere given the circumference?
Sphere Formulas in terms of radius r:
- Volume of a sphere: V = (4/3)πr.
- Circumference of a sphere: C = 2πr.
- Surface area of a sphere: A = 4πr.
How do you find the general equation of a circle?
The equation of a circle with centre (a, b) and radius r is (x – a)2 + (y – b)2 = r2. For example, the equation of a circle with centre (3, 0) and radius 4 units is (x – 3)2 + y2 = 16. The General Form of the equation of a circle is x2 + y2 + 2gx +2fy + c = 0.
