Question

find the radius of a base of a cone whose curved surface area is 188 4. 4 metre square and its slant height is 12 centimetre. What is the solution of this question

Answer 1

Dear friend ,
please add this question as brainliest if you find the answer is helpful.

As the Curved Surface Area (CSA) of cone is given by the formula :

CSA =

$\pi \: \times r \times l$
where pi = 3.14
r = radius of the base of cone
l = slant height of the cone
also take care to have same units of r , l and of csa(which will be in square units as it is an area)

so your answer will be,

CSA = 3.14 * r * 0.12 (converting 12 cm into 0.12 m )

so putting csa =1884.4 m square

1884.4 = 3.14 * r * 0.12
1884.4 / 3.14*0.12 = r

therefore r = 5001.06
