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 $39.4\ cubic\ meter$ .

What is the sixth term of the sequence an=-3•2n+1<br>a6=

muminat

Answer:

$a_6=-384$

Step-by-step explanation:

The $n^{th}$ term of the sequence is given as $a_n=-3\cdot 2^{n+1}$ .

To find the sixth term, which is denoted by $a_6$ , we substitute n=6 into the given rule.

This will give us:

$a_6=-3\cdot 2^{6+1}$

Simplify the exponent to get:

$a_6=-3\cdot 2^{7}$

We simplify further to get:

$a_6=-3\cdot 128$

This simplifies to

$a_6=-384$
