Question

Find the volume of the figure. Round your answer to the nearest tenth if necessary. Use 3.14 for .

Answer 1

Answer:

$\boxed{\rm \: Volume_{(Cylinder)} \approx \: 307.7 \: m {}^{3} } ( \rm \: nearest \: tenth )$

Step-by-step explanation:

Given:

• radius = 7 metres
• height = 2 metres
• π = 3.14

To Find:

• Volume of the cylinder

Solution:

Use the formulae of the volume of cylinder:

$\boxed{\rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h}$

where,

• π = 3.14
• r = radius
• h = height

According to the question:

• radius = 7 metres
• height = 2 metres

Substitute the values onto the formulae in order to find out the volume:

$\rm \: Volume_{(Cylinder)} = \pi(7) {}^{2} (2)$

$\rm \: Volume_{(Cylinder)} = \pi(49)(2)$

$\rm \: Volume_{(Cylinder)} = 98\pi$

$\rm \: Volume_{(Cylinder)} = \: 98 \times 3.14$

$\rm \: Volume_{(Cylinder)} = 307.72 \: m {}^{3} \: (exact \: form)$

$\boxed{\rm \: Volume_{(Cylinder)} \approx \: 307.7 \: m {}^{3} } \: ( \rm nearest \: tenth )$

Hence,we can conclude that:

The volume of the cylinder is approximately

307.7m³.
