ANSWER

EXPLANATION
The sum of the exterior angles of a polygon is 360°
The angles were given in terms of x.
We add all and equate to 360° to obtain.

This implies that,





Answer:

Step-by-step explanation:
Given dimensions:
- Radius of the cylinder = 7 metres
- Height of the cylinder = 3 metres
Given value of π :
To find:
- The Volume of the cylinder
Solution:
Here, we'll need to use the formulae of the volume of cylinder,to find it's volume.Its actually like a savior while solving these type of questions.

where,
- π = 3.14
- r² = (radius)²
- h = height
Plug/substitute them onto the formulae,then simplify it using PEMDAS.
- [We'll substitute the value of π later]



- Now substitute the value of π.



<u>Hence, we can conclude that:</u>
The volume of the cylinder is approximately
461.6 m³.

Answer:
20.2 feet
Step-by-step explanation:
Using Pythagoras theorem, we have
Height^2+13^2=24^2, height=sqrt(407)=20.2
