Question

find L.S.A. T.S.A and volume of cylinder whose base radius is 7 cm and the height is 14 cm​

Answer 1

Step-by-step explanation:

Given:-

cylinder whose base radius is 7 cm and the height is 14 cm.

To find:-

find L.S.A. T.S.A and volume of cylinder whose base radius is 7 cm and the height is 14 cm.

Solution:-

Radius of the base of the cylinder(r)=7 cm

Height of the cylinder(h)=14 cm

1)Lateral surface area of the cylinder=2πrh sq.units

=>LSA=2×(22/7)×7×14 sq.cm

=>LSA=2×22×14 sq.cm

=>LSA=616 sq.cm

2)Total surface area of the cylinder =

2πr(r+h) sq.units

=>2×(22/7)×7×(7+14) sq.cm

=>TSA=2×22×21 sq.cm

=>TSA=924 sq.cm

3) Volume of the cylinder =πr²h cubic units

=>V=(22/7)×7²×14 cu.cm

=>V=22×7×14 cu.cm

=>V=2156 cubic cm

Answer:-

1) LSA of the cylinder=616 cm²

2) TSA of the cylinder=924 cm²

3) Volume of the cylinder=2156 cm³
