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


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 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.

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 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)


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 surface area of a circular cone with a height of 3.76 ft and a base diameter of 5.74?

Entire surface area of a cone = (pi*radius2)+(pi*radius*slant length) Use Pythagoras' theorem to find the slant length


What is the surface area of a right cone with slant height of 12 and a radius of 6?

Total surface area: (pi*36)+(pi*6*12) = 339.292 square units rounded to 3 decimal places. That is assuming that you meant the slant length and not the slant height because otherwise you would need to use Pythagoras' theorem to find the slant length.


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.
