∙ 12y agoSuch a circle is impossible. The radius of a circle is half its diameter.
If the radius of a circle is 2.5 cm, then its diameter is 5 cm long.
Dm
Since 1 dm = 10 cm, 1 dm3 = 103cm3, or 1000 cm3.Since 1 dm = 10 cm, 1 dm3 = 103cm3, or 1000 cm3.Since 1 dm = 10 cm, 1 dm3 = 103cm3, or 1000 cm3.Since 1 dm = 10 cm, 1 dm3 = 103cm3, or 1000 cm3.

Such a circle is impossible. The radius of a circle is half its diameter.
Not sure what is meant by "computed" in this context. The square has an area of 36 square decimetres . A circle with radius 6/sqrt(pi) = 3.3851 dm will have the same area.
The area would be 9*pi, which is approximately 28.26 square dm.
The square.
The answer will depend on what 15 dm represents: the radius, diameter or even circumference!
To derive the moment of inertia of a solid sphere using calculus, you would start by considering a small element of the sphere with volume dV at a distance r from the axis of rotation. Express the mass of this element as dm, then integrate to find the moment of inertia I by summing up the contributions from all such elements. Finally, use the definition of density to express dm in terms of volume element dV, and simplify the integral to obtain the formula for moment of inertia of a solid sphere, which is (2/5)MR^2.
If the radius of a circle is 2.5 cm, then its diameter is 5 cm long.

The area is 63.617 dm2
5.6dm X 5.6dm X 5.6dm is the dimensions of the cube. in meters this is .56m x .56m x .56m. surface are of a cube is the area of one side x 6 or 6s^2 so the surface area would be 188.16 dm^2 or1.8816 m^2 decimeters 5.6^2 x 6 = 188.16 or 5.6 x 5.6 x 6 = 188.16 meters .56^2 x 6 = 1.8816 or .56 x .56 x 6 = 1.8816
πR² * height (If Radius and Height are in decimeter you get the "litres",or else you just have to convert it to dm³ which is a litre)
To calculate this:Look up the Earth's radius. If you find the diameter, divide it by 2. If you find it in kilometers, multiply 10000 to convert to dm. If you find it in meters, multiply by 10 to convert to dm.Use the formula for the volume of a sphere - Earth is approximately sperical - (4/3) x pi x radius3.The result will be in cubic decimeters, which is the same as liters.
