Question

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

Answer 1

Answer:

CSA OF CYLINDER=2pirh

2*22/7*3.5*14

308cm^2

Hope it helps

Step-by-step explanation:

Answer 2

${\textbf{\underline{Curve surface area = 308 cm^2 }}}$

$\huge{\textbf{\underline{Given:-}}}$

Radius of cylinder = 3.5 cm

Height of cylinder = 14 cm

$\huge{\textbf{\underline{To find :-}}}$

Curve surface area of cylinder.

$\huge{\textbf{\underline{Solution:-}}}$

C.S.A of cylinder is = $\large{\textbf{ 2\pi r h }}$

$C.S.A = 2 \times \dfrac{22}{7}\times 3.5 \times 14$

$C.S.A = 2 \times 22 \times 3.5 \times 2$

$C.S.A = 308 cm^2$

$\therefore{\textbf{Curve surface area of cylinder = 308 cm^2 }}$
