A right circular cylinder has radius 3.5 cm and height 14 cm. Find curved surface area

$\Huge\bf\pink{Solution\:!!}$

Radius (r) = 3.5 cm

Height (h) = 14 cm

Curved surface area of the right circulat cylinder = 2πrh

➡ 2 × 22/7 × 3.5 × 14

➡ 44 × 7

➡ 308 cm²

Hence, The curved surface area is 308 cm²

Answer 2

Given,

Radius = 3.5 cm

Height = 14 cm

CSA of cylinder = 2πrh

$= 2 \times \frac{22}{7} \times \times 3.5 \times 14$

$= 44 \times 7$

$= 308 {cm}^{2}$
