a right circulqr cylinder has base radius of 10.5Cm and height 14cm find its tsa​

Answer 1

$\large\bf\underline\red{Question }$

a right circular cylinder has vase radius of 10.5cm and height 14cm . find its TSA .

$\large\bf\underline\red{we\:have}$

➙ radius of cylinder = 10.5 cm

➙ height of cylinder = 14 cm

$\large\bf\underline\red{we\:have\: to\: find}$

❝ TSA ( Total Surface Area) of cylinder ❞

$\large\bf\underline\red{Formula\: used}$

$\mathcal{\small{\fbox{\fbox{\red{TSA of cylinder = 2πr(r+h)}}}}}$

$\large\bf\underline\red{Solution}$

2πr(r+h) = 2 × 22/7 × 10.5 (10.5+ 14)

= 2 × 22 × 1.5 × 24.5

= 2 × 22 × 36.75

= 1617 cm²

therefore the TSA of cylinder = 1617 cm² .

Additional information

➠ CSA of cylinder = 2πrh

➠ volume of cylinder = πr²h
