Question

a wooden monkey of diameter 84 cm has a length of 3.6m.what is the volume of the monkey? express the answer in m3​


​

Answer 1

Answer:

The volume of wooden monkey = 1.995m³

Given:

Diameter of the wooden monkey = 84cm [0.84m]

Length of the wooden monkey = 3.6m

To Find:

The volume of the wooden monkey =?

Solution:

Let's assume that the wooden monkey is roughly in a form of a cylinder. For the cylinder, we know that-

The volume of a cylinder = π r² h(we have length here)

Radius = 0.84/2 = 0.42m

Length is given as 3.6m.

Now, working out with calculations -

$\sf \implies Volume \ of \ cylinder = \dfrac{22}{7} \times 0.42 \times 0.42 \times 3.6$

$\sf \implies Volume \ of \ cylinder = 22 \times 0.06 \times 0.42 \times 3.6$

$\bf \implies Volume \ of \ monkey = 1.995 m^3$

Answer 2

Answer:

Given :-

• Diameter = 84 cm
• Length = 3.6 m

To Find :-

Volume

Solution :-

We know that

100 cm = 1 m

84 cm = 83/100 = 0.84 m

Radius = Diameter/2

Radius = 0.84/2

Radius = 0.42 m

Now

Volume = πr²h

Volume = 22/7 × (0.42)² × 3.6

Volume = 22/7 × 0.42 × 0.42 × 3.6

Volume = 22/7 × 0.1764 × 3.6

Volume = 1.995 m²
