Question

the radius of the cylinder is 28cm and it's height is 65 cm. it's lateral surface area is?​

Answer 1

Step-by-step explanation:

radius = 28cm

height = 65cm

now put these values in formula

$2\pi \: r \: h$

Answer 2

Radius = 28 cm

Height = 65 cm

Cureved/Lateral surface area= 2πrh

= 2 × 22/7 × 28 × 65

= 2 × 22 × 4 × 65

= 44 × 260

= 11440 cm²
