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

What is the slant height of a cone formula?
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.
Find the exact volume of a cone that has a slant height of 26 inches and a radius of 24 inches.?
V = 6,032 cubic inches.
How do you find the missing height or radius of a cone?
you find the radius of a cone by the bottom of it or the round part
How do you find the curved surface area of cone?
Suppose you have a cone with slant height='l' and base radius 'r' and perpendicular height 'h' Curved surface area of COne=pi*r*l =pi*r*(squareroot(r2+h2))
How do you get the slant height of a triangle when you have a height of 5 and a radius of 4?
What do you mean by the radius of 4? Radius is used in circles. Do you mean that the breadth is 4? If so you can use Pythagoras's Theorem to find the 'slant height' (provided that it is a right-angle triangle) (slant height)2=52+42
How do you find the height of a cone if you have the slant height and the radius?
Assuming it is a right cone, use Pythagoras - slant height = hypotenuse, other two sides = radius of base, and height.
How do you find the radius and the slant height of a heap of sand in the shape of cone?
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.
How do you find the slant height of a cone if you have surface lateral and radius?
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.
How do you find the slant height in a cone?
By means of Pythagoras' theorem providing you are given the radius and perpendicular height of the cone
How do you find the height of a cone if you have the slant height and the diameter?
The height would be The square root of the square of the slant surface length minus the square of the radius of the cone at the base.
Find the length of the slant height of a cone with a radius of 15cm and a surface area of 1884cm square?
Slant height is 39.98 cm
Find the volume of the cone?
Label t radius 6cm the height 8cm and the slant height 10cm
How do you find the slant height of a cone if you have the lateral area and slant height?
Why do you need to FIND the slant height if you have the [lateral height and] slant height?
Find the radius of a cone with the slant height of 21 cm and a surface area of 232 pi?
The base radius is 3.517 cm
What is the slant height of a cone formula?
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.
How do you find the radius of a cone when you only have the area and slant height?
The surface area of a cone is the area of the base plus the area of the conical part. This is pi(r2 ) +pi(r)(s)=A If you have A and s, you can solve for r. ( s is the slant height and r is the radius)
What equation do you use to find slant height from altitude and radius?
On the off chance that the question refers to a right cone, l2 = r2 + h2 by Pythagoras, where l is the slant height, h the altitude and r the radius.
