Question

please calculate number 10 for me​

Answer 1

Solution :

We have Provided with a data that ,

The Height of Hollow Wooden Cylinder is 28 cm

Thickness is 1.5 cm

Outer Radius   is 5.5 cm

Finding the Inner Radius of Hollow Wooden Cylinder

⇒ Outer Radius - Thickness

⇒ 5.5 - 1.5

⇒ 4 cm

Finding the Inner Volume

⇒ $\pi r^2h$

⇒ $\frac{22}{7} * 4 * 4 * 28$

⇒ 22 × 16 × 4

⇒ 22 × 64

⇒ 1408 $cm^3$

Therefore , the volume of oil it can hold is 1408 cm^3

Answer 2

Hiii

The Height of Hollow Wooden Cylinder = 28 cm

Thickness = 1.5 cm

Outer Radius  = 5.5 cm

Inner Radius of Hollow Wooden Cylinder

= Outer Radius - Thickness

= 5.5 - 1.5

= 4 cm

Inner Volume

=pi r^2 h

⇒ 22/7 × 4 × 4 × 28

⇒ 22 × 16 × 4

⇒ 22 × 64

⇒ 1408 cm^3

Therefore , the volume of oil it can hold is 1408 cm^3
