What is the surface area of a right cone with a slant height of 6 and a radius of 9?
These dimensions are not possible for a right cone. The radius must be less than the slant height. If we reverse the dimensions (radius 6, slant height 9) the total surface area will be about 282.74 units2
What is slant edge of a cone?
slant edge is a height of a cone
Why is it helpful to know the slant height of a pyramid to find its surface area?
Knowing the slant height helps because it represents the height of the triangle that makes up each lateral face. So, the slant height helps you to find the surface area of each lateral face.
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
What is the volume of a cone with a radius of 6cm and a height of 12cm?
452 cm3 (this assumes you mean 12 cm vertical height, not slant height). If the slant height is 12 cm then the volume changes to 392 cm3.
