"hello students welcome to lido q a video
session
i am saf your math tutor and question
for today is
the radius of the cone is 7 centimeter
area of curved surface is 176 centimeter
square
find the slant height we know that the
radius of the cone is given
and curved surface area is also given so
here
radius of the cone
let us consider it as r which is equal
to 7 centimeter
and curved surface area
of cone let us consider
it as i'll write down here c as a
that is curved surface area which is
equal to 176
centimeter square now we know that
curve surface area is equal to pi rl
hence here we need to find the slant
height
so your slant height l will be equal to
curved surface area
divided by pi into r
which is equal to 176
divided by 22 by 7
into 7
so your slant height l comes out to be
176 divided by that is 176
into 7 divided by 22
into 7 and that is equal to
l is equal to 176 upon 22
that you will simplify and you will get
l is equal to
eight so slant height
of given cone that is
l will be equal to a
centimeter if you have any doubt
you can post it in our comment section
and subscribe to leto for more such
interesting q a
thank you for watching"
