A cone is a solid composed of a circle and its interior (base), a given point not on the plane of the circle (vertex) and all the segments from the point to the circle.A right cone is a cone where the vertex is directly above the centre of the base. If you are talking about a right cone then the radius of the base can be calculated using Pythagorus, a2 + b2 = c2, whereby a = radius, b = height (altitude) and c = slant height.Therefore a2 = c2 - b2 or (radius)2 = (slant height)2 - (altitude)2
The volume of a cone is 1/3 pi times the radius squared times the height. When given the volume and height divide both sides by the height. Volume divided by height is equal to 1/3 times pi times the radius squared. Now divide both sides by 1/3 pi. This will leave you with the radius squared. Take the square root of both sides and you will get the radius.
volume of a cone = 1/3 x pi x radius2 x height Rearrange the formula: height = volume of cone divided by 1/3 x pi x radius2
Around 77 cm2. volume=(one third)(pi)(radius squared)(height)
The "slant height" is called the lateral height.There is no formula. However, if you find the radius of the base and the height of the cone, you can form a triangle. Now use the Pythagorean theorem. Radius2 + height2 = lateral height2.
Assuming it is a right cone, use Pythagoras - slant height = hypotenuse, other two sides = radius of base, and height.
Use the equation for the volume of a cone, replace the known height and volume, and solve the resulting equation for the radius.
volume=pi*radius squared*height/3, where radius is the radius of the cylinder (and will be the radius of the base of the cone),and height is the lenth of the cylinder.
By means of Pythagoras' theorem providing you are given the radius and perpendicular height of the cone
Uisng the lateral area and tha radius, you should be able to find the height of the cone. Using the height and radius as the legs of a right triangle, use the Pythagorean Theorem. The hypotenuse is the slant height.
Volume of a cone = 1/3*pi*radius2*height To find the radius make it the subject of the above formula.
The radius IS given, since height of hemisphere = radius of hemisphere!
You will also need the height of the cone. From circumference you can calculate the radius (circumf/Pi = radius). Volume of cone = 1/3 height x Pi x radius2
You cannot since there is not enough information.
Volume formula for a cone: 1/3*pi*radius squared*height
the slant height of a right circular cone is the distance from any point on the circle to the apex of the cone . The slant height of a cone is given by the formula ,√r2+h2 where r is the radius of the circle and h is the height from the center of the circle to the apex of the cone.
Volume = Base x Height /3 Where base is the area of the base circle (pi*radius*radius) and Height is the perpendicular distance from the base to the apex of the cone
