Question

find the whole surface area of cylinder height 8 cm diameter 14cm​

Answer 1

Answer:

A≈659.73cm²

Explanation:

A=2πd

2h+2π(d

2)2=2·π·14

2·8+2·π·(14

2)2≈659.73446cm²

Answer 2

Answer:

660 sq.cm

Explanation:

here height h=8 cm

diameter=14 cm

that implies radius =7 cm

The surface area of cylinder is 2πr( r+h)

so we get it as;

TSA = 2π.7.(8+7)

= 14 π(15)

= 210π

approximately equal to 210.22/7= 660 sq.cm
