Radius of Base of cylinder = 14 cm
Height of cylinder = 30 cm
Total Surface Area = 2 pi r ( h +r)
= 2 × 22/7 × 14 ( 14 + 30)
= 2 × 22 × 2 ( 44)
= 88 × 44
= 3872 cm^2
Height of cylinder = 30 cm
Total Surface Area = 2 pi r ( h +r)
= 2 × 22/7 × 14 ( 14 + 30)
= 2 × 22 × 2 ( 44)
= 88 × 44
= 3872 cm^2

TSA = 2πrh + 2πr2
= 2πr ( r + h)
= 2 * 22/7 * 14 * (30 + 14)
= 44 * 2 * 44
= 3872
= 2πr ( r + h)
= 2 * 22/7 * 14 * (30 + 14)
= 44 * 2 * 44
= 3872
