Question

the base radius of a cone is 10cm and height is 8cm then what is the slant height of the cone​

Answer 1

Answer:

Step-by-step explanation:

base radius=10cm

height=8

let slant height be l

by using pythogorean theorem

l=sqrt(h^2+r^2)

=(sqrt(10^2+8^2))=sqrt(100+64)=sqrt(164)

=2sqrt(41)
