How big is one piece of paper or are you asking how many kilograms that is 1.5 if I am wrong in any way and you are talking about kilometers please let me know in the comment section hoped that helped and good luck (:
Answer:
- <u>Surface Area = 399.4 m²</u>
- <u>Volume = 1675.5 m³</u>
Step-by-step explanation:
<u>Lateral Surface Area of the Cylindrical Part</u>
- 2πrh
- 2 x π x 5 x 8
- 80 x π
- 251.3 m²
<u>Slant height of cone</u>
- √r² + h²
- √25 + 64
- √89
- 9.43 m
<u>Surface Area of Conical Portion</u>
- πrl
- π x 5 x 9.43
- 47.15 x π
- 148.1 m²
<u>Total Surface Area</u> :
- 251.3 + 148.1
- <u>399.4 m²</u>
<u></u>
<u>Volume</u>
- V = πr²h + 1/3πr²h
- V = πr²h (1 + 1/3)
- V = π x 25 x 8 x (4/3)
- V = π x 1600/3
- V = <u>1675.5 m³</u>
Answer:
x=8
Step-by-step explanation:
6(x+20)=168
6x+120=168
6x=168-120
6x=48
x=48÷6
x=8
The answer is 113.04 because you just have to plug it in to the areaformula which is pi r ^ 2.
