Question

Find volume of tumbler made up of bamboo of height 14cm and diameter of 6cm.

need help jaldi answer kare plz sahi dena
or jinhe nahi aata wo answer na de​

Answer 1

Given -

• Height of tumbler = 14cm

• Diameter of tumbler = 6cm

To find -

• Volume of the tumbler.

Formula used -

• Volume of cylinder = πr²h

Solution -

First as you can see in the question that, the diameter of the tumbler is given, therefore, first we will find the radius of the tumbler. For that we will divide the given diameter with 2, as radius is the half of diameter.

So,

$\longmapsto$ Radius(r) = $\sf\cancel\dfrac{6cm}{2}$

$\longmapsto$ Radius(r) = 3cm

Now,

We have find the radius, so now, we will find the volume of the tumbler. As per the given dimensions, we can see that the tumbler is in the shape of cylindrical, therefore, we will apply the formula of volume of Cylinder.

Volume of cylinder = πr²h

where,

π = $\sf\dfrac{22}{7}$

r = Radius

h = Height

On substituting the values -

Volume = πr²h

$\longmapsto$ Volume = $\sf\dfrac{22}{7}$ × (3)² × 14

$\longmapsto$ Volume = $\sf\dfrac{22}{7}$ × 9cm × 14cm

$\longmapsto$ Volume = 22 × 9cm × 2

$\longmapsto$ Volume = 396cm³

$\therefore$ The volume of tumbler is 396cm³

2 More formule of cylinder -

1. Curved surface area = 2πrh

2. Total surface area = 2πr(r + h)

Answer 2

Given :-

• A bamboo whose height is 14 cm and diameter is 6 cm.

To Find :-

• What is the volume of tumbler.

Formula Used :-

✪ Volume of cylinder = πr²h ✪

Solution :-

Given :

Height = 14 cm

Diameter = 6 cm

❶ First we have to find the radius,

We know that,

↦ Radius = Diameter ÷ 2

↦ Radius = 6 ÷ 2

➠ Radius = 3 cm

❷ Now we have to find the volume,

According to the question by using the formula we get,

⇒ Volume = 22/7 × (3)² × 14

⇒ Volume = 22/7 × 3 × 3 × 14

⇒ Volume = 22/7 × 9 × 14

⇒ Volume = 22/7 × 126

➠ Volume = 396 cm²

∴ The volume of tumbler is 396 cm³ .
