Volume = l x w x h

(Mon) A room measures 8.6 m wide by 12.4 m long by 4.1 m high. What is the volume of the room in cm 3 (5 pts / 5 min). (Mon) A room measures 8.6 m wide by 12.4 m long by 4.1 m high. What is the volume of the room in cm 3. Volume = l x w x h. Vol = (8.6m)(12.4m)(4.1m). Vol = 437.22 m 3.

  1. (Mon) A room measures 8.6 m wide by 12.4 m long by 4.1 m high. What is the volume of the room in cm3 (5 pts / 5 min)

  2. (Mon) A room measures 8.6 m wide by 12.4 m long by 4.1 m high. What is the volume of the room in cm3 Volume = l x w x h Vol = (8.6m)(12.4m)(4.1m) Vol = 437.22 m3 100 cm 100 cm 100 cm 437.22 m3 1 m 1 m 1 m Vol = 4.37 x 108 cm3

  3. (Tue) You are standing 10 m from a tree. If you look up at an angle of 44.5° you see the top of the tree. How tall is the tree? (5 min / 5 pts)

  4. (Tue) You are standing 10 m from a tree. If you look up at an angle of 44.5° you see the top of the tree. How tall is the tree? Tanθ = Opp/Adj Tan(θ) = Height/Distance Tan(44.5°) = Ht/10m (10m)tan(44.5°) = Ht Height = 9.83 m

  5. (Wed) If you drive your car with an average velocity of 48.0 km/hr to the east, how long will it take you to drive 144 km on a straight highway? (5 min / 5 pts)

  6. (Wed) If you drive your car with an average velocity of 48.0 km/hr to the east, how long will it take you to drive 144 km on a straight highway? (5 min / 5 pts) v = Δx/Δt 48.0 km/hr = 144 km/Δt Δt = 144 km / 48.0 km/hr Δt = 3.0 hrs +1 Just ‘cause

  7. (Thu) If you were to travel northeast (45°) for 22.3 km and then traveled south (180°) for 15.3 km, how far would you be from where you started and in what direction? (10 min / 10 pts)

  8. (Thu) If you were to travel northeast (45°) for 22.3 km and then traveled south (180°) for 15.3 km, how far (& direction) would you be from where you started? (10 min / 10 pts) x1 = 22.3(cos45°) 1 2 y1 = 22.3(sin45°) x2 = 15.3(cos(-90°)) 15.76 15.76 Tot y2 = 15.3(sin(-90°)) 0.00 -15.30 tanθ =opp/adj θ =tan-1(opp/adj) 15.76 0.46 θ =tan-1(0.46/15.76) x = length(cosθ) x² + y² = tot² θ = 1.67° y = length(sinθ) Tot = (15.76² + 0.46²)1/2 Tot = 15.76 km θ = 88.33° Fm N

  9. (Fri) Take this time for some last minute review before the test.
