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 values of b satisfy 3(26 + 3)² = 36?

MakcuM [25]

The numeric value of the b is 0.23 which satisfy the given equation.

According to the statement

We have to find that the value of the b.

So, For this purpose, we know that the

The numeric value refers to the worth of each digit depending on where it lies in the number.

From the given information:

The equation is a

3(2b + 3)² = 36

then to find the value of b rearrange the terms then

(2b + 3)² = 12

(2b + 3) = \sqrt{12}

(2b) = \sqrt{12} -3

then

b = \sqrt{12} -3/ 2

b = 3.46 - 3/2

b = 0.46/2

b = 0.23.

So, The numeric value of the b is 0.23 which satisfy the given equation.

Use the graph of the exponential growth function f(x) = a(2x) to determine which statement is true. f(0) = 2 when a = . f(0) = 3

Genrish500 [490]

If the function is exponential, then (2x) is the exponent.

f(x) = a^(2x)

Take it from here.

Sue graphed the formula for converting temperatures from Fahrenheit to Celsius.If the temperature is 50 degrees Fahrenheit, what

kherson [118]

Answer:

10°C

Step-by-step explanation:

The temperature is 50°F

Let's assume that 50°F = x°C

The formula is;

(x°C × $\frac{9}{5}$ ) + 32 = 50°F

$\frac{9}{5}$ x°C = 50 - 32 = 18

$\frac{9}{5}$ x°C = 18

x°C = $\frac{5}{9}$ × 18 = 10°C

So 50°F is equal to 10°C.
