What is radius of a 40 diameter hole?
the answer is 20
How much dirt is in a hole that is 3 feet in diameter and 5 feet deep?
As it is a hole there is no dirt in it. However, a cylinder of dirt with radius 1.5ft, depth 5ft and a volume of πr2h ~= 35.34 cu ft has been removed.
The hole is in the shape of a cylinder whose volume is approximately 4400 cubic feet and whose height is 3.4 miles find the radius of the hole to the nearest hundredth of a foot?
3.4 miles is 17952ft r2 = 4400/17952pi r= 0.28 ft
How do you find the area of a compact disc?
Suppose the diameter of the disk is D cm so that the radius is D/2 = R cm. Suppose the diameter of the hole is d cm so that its radius is d/2 = r cm. Then the area of one side of te disc is pi*(R^2 - r^2) Therefore the total area of the two sides is 2*pi*(R^2 - r^2) square cm. This ignores the surface area of the edge which, although small, is not 0.
Is radius half radius?
No. Radius is half of the diameter.
What is the radius of a black hole singularity?
If it had a radius, then it wouldn't be a singularity. The event-horizon surrounding a black hole has a radius, which depends on the black hole's mass. But the singularity itself has no radius.
The radius of the event horizon of a black hole is called the?
Schwarzschild radius.
What of a black hole is the radius from a black hole at which the escape velocity is approximately equal to the speed of light?
It is called the Schwarzschild radius
What black hole property determines the schwarzschild radius of a black hole?
The black hole property that determines the Schwarzschild radius of the black hole is that it has mass but no angular momentum nor electric charge.
Which of these objects has the largest radius a 1.2M rm Sunwhite dwarf a 1.5M rm Sun neutron star a 3.0M rm Sun black hole?
The black hole with a mass of 3 solar masses has the largest radius among the objects listed. This is because the radius of a black hole is determined by its mass and the Schwarzschild radius formula, which dictates that the radius of a black hole increases with its mass.
What is radius of a 40 diameter hole?
the answer is 20
What is Schwarzchild radius of a 2 solar mass black hole is about?
The Schwarzchild radius of a 2 solar mass black hole would be about 5.9 km.
How big is the hole in gymkhana keyhole?
the hole has a 20 foot diameter and a 10 foot radius
What is the significance of the Schwarzschild radius?
Well, darling, the Schwarzschild radius is basically the point of no return around a black hole where not even light can escape. It's like the ultimate "do not enter" zone in space. So, if you ever find yourself approaching a black hole, you better hope you don't cross that radius unless you want to be spaghetti-fied into oblivion.
Where are the horizons within black holes located?
The event horizon of a black hole is a spherical area round the center of the black hole; it has a radius proportional to the mass of the black hole - a radius of about 2.95 kilometers for every solar mass.
How do you calculate the radius of a 7 solar mass black hole?
The radius of a black hole can be calculated using the formula for the Schwarzschild radius, which is given by Rs = 2GM/c^2, where G is the gravitational constant, M is the mass of the black hole, and c is the speed of light in a vacuum. Plugging in the values for a 7 solar mass black hole (M = 7 solar mass), the Schwarzschild radius would be approximately 20.98 km.
What does the black hole?
The black hole represents a crust in the space which swallows anything that passes through it. Even light cannot escape from a black hole! There is a particular radius for a mass to become a black hole when it is squashed. This is known as the Schwarzschild radius and for the body to become a black hole, the escape velocity must equal or exceed speed of light!
