ANY BODY ANSWER
Find volume of right circular cylinder whose radius 7cm and h = 20cm.
​

Answer 1

Answer:

• 3080cm³ is the required volume of Cylinder

Step-by-step explanation:

According to the Question

It is given that,

• Radius of cylinder ,r = 7cm
• Height of cylinder ,h = 20cm

we have to calculate the volume of right circular cylinder .

• Volume of Cylinder = πr²h

substituting the value we get

⇢Volume of Cylinder = 22/7 × 7 ×7 × 20

⇢ Volume of Cylinder = 22×7×20

⇢ Volume of Cylinder = 154 × 20

⇢ Volume of Cylinder = 3080 cm³

• Hence, the volume of Cylinder is 3080cm³.

Answer 2

$\underline{\rm Given \: \: Data }:$

In a Right Circular Cylinder,

Radius (r) = 7cm

Height (h) = 20cm

$\underline{ \rm To \: \: Find} :$

Volume of Right Circular Cylinder (V)

$\underline{ \rm Solution} :$

By using,

$\boxed{ \boxed{ \color{lime} \bf Volume = \pi {r}^{2} h}}$

then, by substituting the values

$\rm⇒ \: \: V = \frac{22}{ \cancel7} \times \cancel7 \times 7 \times 20$

$\rm⇒ \: \: V = 22 \times 7 \times 20$

$\boxed{ \color{pink}\bf V = 3080 \: {cm}^{3} }$

FINAL ANSWER :

Volume of Right circular cylinder is 3080 cm³ .
