What term does perpendicular lines use

Travka [436]

Answer:

Hello, In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.

The volume of a right circular cone that has a height of 13 m and a base with a diameter of 3.4 m. Round your answer to the near

Mamont248 [21]

Answer:

The volume of right circular cone having height = $13 \ m$ and Diameter = $3.4 \ m$ is $39.4\ cubic\ meter$ .

Step-by-step explanation:

Diagram of the given scenario is shown below.

Given that

Height of a right circular cone is $13 \ m$ .

Diameter of the right circular cone is $3.4 \ m$ .

To find: The volume of a right circular cone.

So, From the question,

$Height = \ 13 \ m\\diameter = 3.4\ m$

$Radius = \frac{diameter}{2}= \frac{3.4}{2}$

⇒ $Radius = 1.7\ m$

Now

Volume of right circular cone = $\frac{1}{3}\pi r^{2}h$

$=\frac{1}{3}\times\frac{22}{7} \times (1.7)^{2}\times 13$

= $\frac{826.54}{21}$

$= 39.4\ cubic\ meter$ .

Therefore,

The volume of right circular cone having height = $13 \ m$ and Diameter = $3.4 \ m$ is $39.4\ cubic\ meter$ .
