Question

find the volume of circular cylinder whose height is 15 cm and radius of the base is 7cm
​

Answer 1

$\huge{\underline{\underline{\mathtt{\orange{Given}}}}}$

Circular cylinder whose height is 15 cm and radius of the base is 7cm

$\huge{\underline{\underline{\mathtt{\orange{To\:find}}}}}$

Volume of circular cylinder

$\huge{\underline{\underline{\mathtt{\orange{Solution}}}}}$

Volume of circular cylinder

$\implies\sf πr^2h$

$\implies\sf \frac{22}{7}×7×7×15$

$\implies\sf 22×7×15=2310cm^3$

$\huge\underline\frak\red{Note}$

• Volume of cylinder = πr²h
• Curved surface area of cylinder=2πrh
• Total surface area of cylinder=2πrh+2πr²

Answer 2

Answer:

Given :-

Height of Cylinder (h) = 15 cm

Radius of Cylinder (r) = 7 cm

To Find :-

Volume of Cylinder

Solution :-

Volume of Cylinder = πr^h

$= = > \pi {r}^{2} h = \frac{22}{7} \times 7 \times 7 \times 15 \\ = = > 22 \times 7 \times 15 \\ = = > 2310 {cm}^{2}$

More Formula for Cylinder:-

• Volume of Cylinder = πr^h

• Curved Surface Area = 2πrh

• Total surface Area = 2πrh +2 πr^2 = 2πr(h +r)
