Answer:
Step-by-step explanation:
$7.25 - $5.75 = $1.50
$1.50 ÷ $0.50 = 3
Radius = Diameter ÷ 2 = 10 ÷ 2 = 5mm
<u>
Find Volume: </u>
Volume= πr²h
Volume = π (5)² (6) = 471.24mm³ (Nearest hundredth)
<u>Find Surface Area:</u>
Surface area = 2πr² + 2πrh
Surface area = 2π(5)² + 2π(5)(6) = 345.58 mm²
Answer: Volume = 471.24mm³ , Surface area = 345.58 mm²
We first find out time taken to travel for just 1 km
2hrs is equivalent to 120 minutes
120 km = 120 min
1 km = x (where x is the time taken to travel 1 km).
we simplify the equation by cross - multiplying the equation , so:
120 × x = 1 × 120 → 120x = 120 → x = 120/120 → x = 1
So the car covers 1km in 1 minute
For 300 km the car will take 300 × 1 minute = 300 minutes
we convert minutes to hours by dividing by 60 → 300 / 60 = 5
Therefore the car will take 5 hours to cover 300 km.
