Given
h = 7cm
volume of cylinder = 4950 cu cm
r = ?
volume of cylinder =
r*rh
= 22/7*r2*7 = 4950
= 22r2 = 4950
= r2 = 4950/22
= r2 = 225
= r =
225
= r = 15
h = 7cm
volume of cylinder = 4950 cu cm
r = ?
volume of cylinder =
= 22/7*r2*7 = 4950
= 22r2 = 4950
= r2 = 4950/22
= r2 = 225
= r =
= r = 15

Volume of cylinder = 4950 cm³
πr²h = 4950
22/7 × r² × 7 = 4950
r² × 22 = 4950
r² = 4950/22
r² = 225
r² = 15²
r = 15
the radius of it's base = 15 cm
πr²h = 4950
22/7 × r² × 7 = 4950
r² × 22 = 4950
r² = 4950/22
r² = 225
r² = 15²
r = 15
the radius of it's base = 15 cm
