Question

if the diameter of a solid cylinder of length 1 40 centimetre is 8 find its curved surface area​

Answer 1

Answer:

CSA = 2πrh

2× 22/7 ×4 ×140

and now u may solve and get answers

Answer 2

Answer:

3520 cm²

Explanation:

Curved area surface of cylinder: 2πrh

R = Diameter/2 = 8/2 = 4cm

Height (Length) = 140 cm

2πrh = 2 * 22/7 * 4 * 140

CSA = 3520 cm² [ After calculating the values in the formula]
