Hi ,
Let r and h are radius and height
of the cone .
area of the base = 154 cm²
π r² = 154
22/7 × r² = 154
r² = ( 154 × 7 ) / 22
r² = 7 × 7
r = 7 cm
Volume = ( π r² h ) /3
V = ( 22 × 7 × 7 × h ) / ( 7 × 3 )
= ( 22 × 7 × h ) / 3 cm³
Plz , send the ratio , then only
we get the value .
I hope this helps you.
