$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Question}}}}}}$
find the curved surface area of a right circular whose heightis 13.5 cm and radius of it's base is 7 cm. also find it's total surface area
​

Answer 1

Step-by-step explanation:

Curved surface area = 2πrh

= 2 × 22/7 × 7 ×13.5

=594cm²

TSA of cylinder=²πr(h+r)

=2 × 22/7 × 7 (13.5+7)

=2 × 22 × 20.5

=902cm²

Answer 2

Step-by-step explanation:

C.S.A= 2πrh

= 2×22/7×7×13.5

=2×22×13.5

= 44×13.5

= 594cm²

T.S.A= 2πr(h+r)

= 2×22/7×7(13.5+7)

=2×22(20.5)

=44×20.5

=902cm²
