Answer:
c ≈ 4.2 ft
Step-by-step explanation:
Using the cosine rule with a = 7, b = 8 and C = 32°, then
c² = 7² + 8² - (2 × 7 × 8 × cos32°)
= 49 + 64 - (112 × cos32°)
= 113 - 94.98
c = ≈ 4.2 ft ( to the nearest tenth )
Volume of cylinder = πr²h
Volume = 3.14 x 4² x 20
Volume = 1,004.8 m³
When the tank is 60% full, the volume is:
0.6 x 1004.8
= 602.88 m³ of water
Answer: A=2x²+18x+30
Step-by-step explanation:
To find the area, we multiply the length and the width. We can do that with the picture provided.
A=(5+x)(6+2x) [use FOIL method to distribute/multiply]
A=30+10x+6x+2x² [combine like terms]
A=30+18x+2x²
