Question

what is the volume of a cylinder if its diameter is 34.3 cm and height is 8.3 cm

Answer 1

Question :-

what is the volume of a cylinder if its diameter is 34.3 cm and height is 8.3 cm.

Answer :-

→ the volume of cylinder is 6470.700

To Find :-

→ Volume of cylinder

Formula used :-

$\rightarrow \sf{volume \: of \: cylinder \: = \pi \: {r}^{2} h}$

_______________________________

Step - by - step explanation :-

Given that ,

• Diameter (d) = 34.3 cm ,hence radius is d/2 = 17.15

• Height (h) is 8.3 cm

• Volume of cylinder (v) = ?

Substitute these values in the given formula,

$\rightarrow \sf{v = \pi \: \: {(17.15)}^{2} \times 8.3} \\ \\ \rightarrow \sf{ v \: = \pi \: \times 294.1225 \times 8.3} \\ \: \\ \because \: \pi \: = \frac{22}{7} \\ \\ \rightarrow \sf{ v \: = \frac{22}{7} \times 294.1225 \times 8.3} \\ \\ \rightarrow \sf{ \: v \: = 42.0175 \times 154} \\ \\ \rightarrow \sf{v \: = 6470.695} \\ \\ \sf{in \: round \: figure} \\ \\ \rightarrow \boxed{\sf{ v \: = 6470.700}}$

Therefore the volume of cylinder is

6470.700

Answer 2

ANSWER:-

Given:

• The diameter of cylinder is 34.3cm
• The height of cylinder is 8.3cm

To find:

The volume of cylinder.

Explanation:

We know that radius= $\frac{Diameter }{2}$

Radius= $\frac{34.3}{2}$

Radius= 17.15cm

Therefore,

Formula of the volume of cylinder: πr²h

⇒Volume of cylinder= $\frac{22}{7} ×17.15×17.15×8.3$

⇒Volume of cylinder= $\frac{53706.76}{7} cm^{2}$

⇒ Volume of cylinder= 7672.39cm²
