Question

find the volume of a right circular cylinder having radius 8cm and hheights 10cm

Answer 1

Answer :

• 2011.4 cm³ is the Volume of right circular cylinder.

Given :

• Radius is 8cm
• Height is 10cm

To find :

• Volume of right circular cylinder

Solution :

To find the volume of a right circular cylinder we have to use the formula of volume then we get answer of volume of a right circular cylinder

Here,

• Radius = 8cm
• Height = 10cm

We know that,

• Volume of cylinder = πr²h

Where , r is radius and h is height

》Volume of cylinder = πr²h

》22/7 × (8)² × 10

》22/7 × 8 × 8 × 10

》22/7 × 64 × 10

》22/7 × 640

》2011.4 cm³

Hence , 2011.4 cm³ is the Volume of right circular cylinder.

Answer 2

Given:-

• Radius of a right circular cylinder = 8cm

• Height of a right circular cylinder = 10cm

To find:-

• Volume of right a Circular Cylinder

Formula Used:-

• ${\boxed{\bf{Volume\: of\: cylinder \:= \pi r^2h}}}$

Solution:-

Using Formula,

$\sf :\implies\:Volume\: of\: cylinder \:= \pi r^2h$

Putting values,

$\sf :\implies\:Volume\: of\: cylinder \:= \dfrac{22}{7}\times 8^2 \times 10$

$\sf :\implies\:Volume\: of\: cylinder \:= \dfrac{22}{7}\times 64 \times 10$

$\sf :\implies\:Volume\: of\: cylinder \:= \dfrac{10,480}{7}$

$\sf :\implies\:Volume\: of\: cylinder \:= 2011.42 \:cm^3$

Hence, The Volume of right circular cylinder is 2011.42cm³.
