hey friend here are the formulas
lsa of frustum- pi into (r1 + r2) into slant height or l
vol of frustum- pi into height/3 { (r1)squared + (r2)squared + r1r2 }
tsa of frustum- pi into (r1 + r2) into slant height or l + pi (r1)squared + pi(r2)squared
lsa of frustum- pi into (r1 + r2) into slant height or l
vol of frustum- pi into height/3 { (r1)squared + (r2)squared + r1r2 }
tsa of frustum- pi into (r1 + r2) into slant height or l + pi (r1)squared + pi(r2)squared
pramod22:
send me direct formula
all signs are pls
positive
but also send me direct formula i will mark u as a brillalist

1. Volume of frustum of cone
= πh / 3[R2 + r2 + Rr] cubic unit
2. L. S. A or C. S. A = πl(R + r) Sq units where l2= h2 + (R – r)2
3. T. S. A = πR2 + πr2 + πl(R + r) Sq. units.
(Area of base + Area of top + Area of lateral )
4. Slant height (l) = √h22 + (R – r)2
= πh / 3[R2 + r2 + Rr] cubic unit
2. L. S. A or C. S. A = πl(R + r) Sq units where l2= h2 + (R – r)2
3. T. S. A = πR2 + πr2 + πl(R + r) Sq. units.
(Area of base + Area of top + Area of lateral )
4. Slant height (l) = √h22 + (R – r)2
