Question

formula of frustum.....

Answer 1

Answer:

Step-by-step explanation:

1 2 ( 2 π R + 2 π r ) l = π ( R + r ) l. l , being the slant height of the frustum, and being the two radii of bases. Note: (1) Total surface area of the frustum of a cone. = π R 2 + π r 2 + π ( R + r ) l.

Answer 2

area of frustum = 22/7(R+r) ‹/(R-r) ²+h²

volume of frustum= 22/7/h(R²+r²+R*r)


guys here I used 22 by 7 for the value of Pie...
