Question

Q. Find the curved surface and total curved surface area of cylinder ( a ) Diameter = 14cm ( b ) Height = 15cm​

Answer 1

Answer:

968 sq. cm

Step-by-step explanation:

radius of cylinder ( r) = 14/2 cm

= 7 cm

height of cylinder ( h) = 15 cm

total surface area of cylinder = 2πr(h+r)

=

$2 \times 22 \div 7 \times 7(15 + 7)$

$44 \times 22 = 968$

therefore, total surface area of cylinder = 968 sq. cm
