Question

Four times the area of the curved surface of a cylinder is equal to 6 times the sum of the areas of its bases .if its height is 12cm, find its curved surface area.​

Answer 1

Answer:

Step-by-step explanation:

4 ×2πrh = 6 ×2 × πr²

4h = 6r

4 × 12 = 6 × r

r = 8cm

Curved S Area = 2πrh

= 2 × 3.14 × 8 × 12

= 602.88 cm²
