Question

The diameter of a cylinder is 18.5cm and length is 6.1m find the surface area of curved surface​

Answer 1

Answer:

35434.9 cm^2

Step-by-step explanation: radius (r) = 18.5/ 2

= 9.25cm

Curved surface area of cylinder = 2π r h

= 2× 3.14× 9.25 ×610

= 35434.9 cm^2

Q. The diameter of a cylinder is 18.5cm and length is 6.1m find the surface area of curved surface.

✯Given :-

• Diameter of the cylinder is 18.5cm
• length/height = 6.1m or, 610cm

✧To Find :-

• Curved surface area of the cylinder

$\bold{ the \: diameter \: is \: 18.5cm \: then \: radius \: will \: be \: = \frac{18.5}{2} = 9.25cm} \\ \tt \ \green{ \therefore{ \underline \bold{ formula = area \: of \: curved \: surface \: area = 2\pi \times rh}}} \\ \tt \: 2 \times \frac{22}{7} \times 9.25 \times 610 = 35434.9cm^2 \:\:☞ans.$

$\huge\underline\mathfrak\purple{\therefore{ ✯Curved\: surface \:area = 35434.9cm^2</p><p>.}}$
