What formula do you use to find the volume the regular shape?
Sphere: 4/3*pi*r3 Tetrahedron: s3*sqrt(2)/12 Cube: s3 Octahedron: s3*sqrt(2)/3 Dodecahedron: s3*[15+7*sqrt(5)]/4 Icosahedron: s3*5/12*(3+sqrt(5) where r is the radius and s is the length of each edge.
What is the radius of 1017.36 if i already did the area?
The question is stated as if in the presence of excessive background noise.If we're talking about a circle, and if '1,017.36' is its area, then we can find the radius like this:1,017.36 = pi R2Divide each side by pi:1,017.36 / pi = R2Take the square root of each side:R = sqrt( 1,017.36 / pi ) = 17.99544(rounded)=====================================We're guessing that the given radius was 18, and some arithmetic errors crept induring the process of finding the area.If the radius is 18, thenArea = pi R2 = 324 pi = 1,017.88 (rounded)Working backward from 1,017.88, we would get 18.00004 for the radius.
A right triangle is insribed in a circle of radius 3 the length of the hypotenus of the right triangle is?
Pythagoras! Two sides of the triangle must each be equal to the radius, ie 3 so Hypotenuse = sqrt(3^2 + 3^2) =sqrt 18 = 4.243
How many lead balls each of radius 1 cm can be made from a sphere of radius 8 cm?
83 = 512
What would the radius be if you have square root of 354?
That depends. What is that "square root of 354" ? Is it the circumference ? Diameter ? Area of the circle ? Area of the sphere ? Volume of the sphere ? The radius is different for each one.
How many spheres of mercury each with a radius of r should combine to form a single sphere with a radius of 3r?
Volume of the sphere varies as the cube of the radius.Tripling the radius increases the volume by a factor of (3)3 = 27.It takes 27 spherical volumes with radius 'r' to fill one spherical volume with radius '3r'.
How many lead ball each of radius 1 cm can make a sphere of radius 8 cm?
The volume of a sphere is 4/3*pi*r3 So Vol8/Vol1 = 83/13 = 83 = 512

How can you find the height of a cylinder that contains 3 tennis balls with a radius of 3cm?
If the radius of each tennis ball is 3cm, then the diameter of each ball would be 6 centimeters. And since there are 3 balls, the height of the cylinder would be 18 centimeters.
What is the relationship between polyhedra and solids?
Each polyhedron is a kind of solid object. Some solid objects -- for example, a sphere or a torus -- are not polyhedra, but every solid object can be closely approximated with a polyhedra.
Will a solid metal sphere hold greater charge then a hollow sphere of the same diameter where does the charge reside in each case?
both will have same charge, in both caes charge will reside on surface.
Joshua and Isabella are having a snowball fight. Joshua has a snowball shaped as a sphere with a radius of 6 cm. Isabella also has spherical snowball with a radius of 3 cm. Find the volume of each sno?
The volume of a sphere can be calculated as:volume = (4/3) x pi x radius cubed Simply replace the given radius, and do the calculations.
What is the volume of a cylinder with ends that are half spheres with a radius of 4 and has a height of 12?
Each half-sphere occupies a height of 4. Effectively, there is a full sphere of radius 4 and a cylinder of length 4. The volume of the sphere = 4/3πr³ = 4/3π4³ = 268.08 The volume of the cylinder = πr²h = π4² x 4 = 201.06 Total volume = 268.08 + 201.06 = 469.14 (2dp)
What is the radius if the volume of a sphere is 250 cubic inches?

How big is a sphere with a volume of 1.36 billion kilometers?
As we're all acutely aware, the volume of a sphere in terms of its radius is V = 4/3 (pi) (radius)3 In your question, the volume is given, and the radius is to be yet found. We can use the same formula, but first, we have to massage it in order to highlight the radius as the dependent variable. Multiply each side of the formula by 3/4 pi : 3 V/4 pi = (radius)3 Take the cube root of each side: Radius = cube root of (3 V/4 pi ) or, if you need it made even easier ... Radius = 0.62035 (Volume)1/3 The rest is trivial. There's no doubt whatsoever that you can do it quickly on your own. Also, by the way . . . "kilometers" are not a volume. "Cubic kilometers" are.
