Question

Find the volume of a cylinder whose radius is 7cm and height is 6cm

Answer 1

Step-by-step explanation:

solid cylinder-

h=7cm

r=6 cm

⭕️volume of cylinder= Π × r² × h

=22/7 × 6 × 6 × 7

= 22 × 36

=792 cm³

⭕️conical cavity-

h=7cm

r=6cm

⭕️vol. of cone= 1/3 × π × r² × h

= 22 × 36 / 3 = 264 cm

⭕ ∴ ️volume of the remaining solid= volume of cylinder-volume of conical cavity

=792-264

∴ = 528cm³

Answer 2

Given : Radius and height of a cylinder are 7cm and 6cm

To Find : Volume of the cylinder.

⠀⠀⠀⠀⠀____________

Here

• Radius of the cylinder = 7cm
• Height of the cylinder = 6cm

As we know that :

• Volume of a cylinder = πr²h

⠀⠀⠀⠀⠀____________

Where, r denotes radius of the cylinder and h denotes height of the cylinder.

Now, put the values in the formula and solve.

=> Volume of the cylinder = πr²h

=> Volume of the cylinder = 22/7 × 7 × 7 × 6

=> Volume of the cylinder = 22 × 7 × 6

=> Volume of the cylinder = 924 cm³

∴ Hence, the volume of the cylinder is 924cm².
