Each number is the previous number plus 5 ( 8 + 5 = 13, 13 + 5 = 18), so the next item would be 18 + 5 = 23

Find the area of the blue sectors formed by angle DFE. Round answer to

iren2701 [21]

Answer:

<h2>1525.7 square meters, approximately.</h2>

Step-by-step explanation:

Notice that the radius is 28 meters, and the angle of the orange sector is 137°. However, the angle of the blue sector is:

360° - 137° = 223°

The area of a circular sector is

$A=\frac{\pi r^{2} \alpha}{360\°}$

Replacing given values, we have

$A=\frac{(3.14)(28)^{2} (223\°)}{360\° }=\frac{548972.48}{360} \approx 1525$

Therefore, the right answer is the second choice.

HELPPP PLSSS!!!!!!!!!!! Find the volume of the cone.

Katen [24]

Answer:

The volume of cone is $\boxed{\tt{167.47}}$ unit³.

Step-by-step explanation:

<u>Solution</u> :

As per given question we have provided :

➝ Radius of cone = 4 units
➝ Height of cone = 10 units

Here's the required formula to find the volume of cone :

${\longrightarrow{\pmb{\sf{V_{(Cone)} = \dfrac{1}{3}\pi{r}^{2}h}}}}$

V = Volume
π = 3.14
r = radius
h = height

Substituting all the given values in the formula to find the volume of cone :

${\longrightarrow{\sf{Volume_{(Cone)} = \dfrac{1}{3}\pi{r}^{2}h}}}$

${\longrightarrow{\sf{Volume_{(Cone)} = \dfrac{1}{3} \times 3.14{(4)}^{2}10}}}$

${\longrightarrow{\sf{Volume_{(Cone)} = \dfrac{1}{3} \times 3.14{(4 \times 4)}10}}}$

${\longrightarrow{\sf{Volume_{(Cone)} = \dfrac{1}{3} \times 3.14{(16)}10}}}$

${\longrightarrow{\sf{Volume_{(Cone)} = \dfrac{1}{3} \times 3.14 \times 16 \times 10}}}$

${\longrightarrow{\sf{Volume_{(Cone)} = \dfrac{1}{3} \times 3.14 \times 160}}}$

${\longrightarrow{\sf{Volume_{(Cone)} = \dfrac{1\times 3.14 \times 160}{3}}}}$

${\longrightarrow{\sf{Volume_{(Cone)} = \dfrac{3.14 \times 160}{3}}}}$

${\longrightarrow{\sf{Volume_{(Cone)} = \dfrac{502.4}{3}}}}$

${\longrightarrow{\sf{Volume_{(Cone)} \approx 167.47}}}$

$\star{\underline{\boxed{\sf{\purple{Volume_{(Cone)} \approx 167.47\: {unit}^{3}}}}}}$

Hence, the volume of cone is 167.47 unit³.
