A cone has a circular base, a perpendicular height of 21cm and a semi vertical angle of 300. Calculate the slant height of the cone. Find the area of its base (Take π = 22/7)

Step-by-step explanation:

GIVEN: A cone has a circular base, a perpendicular height of and a semi vertical angle of .

TO FIND: Calculate the slant height of the cone. Find the area of its base.

SOLUTION:

Consider the figure attached.

Let the  radius of cone be

Now,

area of base

Hence Area of base of cone is

i think this could be a possible answer (1 / 84) -1
