Question

Base circumference of a cylinder is 13 2 m and its height is 2m . Find its curved surface
area .

Answer 1

Answer:

Volume of a Cylinder = Area of base x Height of cylinder. Circumference of base = 132 cm.

Answer 2

$\large\green{\underline{\underline{\bf{\red{Given}}}}}$

• Base circumference of a Cylinder =132 m

• Height(h) of Cylinder = 2 m

$\large\green{\underline{\underline{\bf{\red{To Find}}}}}$

• Curved Surface Area of Cylinder

$\large\green{\underline{\underline{\bf{\red{Solution}}}}}$

As we know that,

The base of the cylinder is circular in shape

Circumference of Circle = 2πr

$\implies \: 2\pi \times r \: = 132 \\ \\ \implies \: r = 132 \times \frac{7}{22} \times \frac{1}{2} \\ \\ \implies \: r = 21m$

Now,

• Radius(r) of Cylinder = 21 m

We know that,

Curved Surface Area of Cylinder

= 2πrh

= 2 × 22/7 × 21 × 2

= 264 m^2

$\large\green{\underline{\underline{\bf{\red{Some\:thing\:more\:about\:Cylinder:}}}}}$

• Total Surface Area = 2πr(h+r)

• Curved Surface Area = 2πrh

• Volume = πr^2h

where,

r = radius

h = height of Cylinder
