Question

if TSA of a cone of radius is 7cm is 704cm^2 then find the slant height
​

Answer 1

Answer:

Slant height of a cone is 25m

Step-by-step explanation:

Let slant height of a cone be 'l'

ATP,

πr(r+l)= total surface area of cone

22/7*7(7+l)=704

22(7+l)=704

7+l=704/22

7+l=32

l= 32-7

l=25

slant height =25m
