First, we get the area of the whole rectangle, easy enough:
18 * 16 = 288 cm²
Now, for the area of the circle, we use the circle area formula:
Area = pi * r²
Area = 3.14 * 6² = 3.14 * 36 = 113.04cm²
Now we substract the circle area from the rectangle area:
Shaded region = 288 - 113.04 = 174.96cm²
Answer:
$25,875
Explanation:
To find 15% of the price of the vehicle we just simply multiple the original price by the percentage in its decimal form.
22,500(0.15)=3,375
We then add that to the original total to get the new total.
22,500+3,375=25,875
We must look at this question in steps
The first half of the journey is travelled at 40 km/h
Half of 100km is 50 km
Using the formula
Distance = Speed x Time
Speed = Distance / Time
Time = Distance / Speed
We can work out the time:
50km / 40km/h = 1.25 hours
Next we look at the second half of the journey
50km at 80km/h
50km / 80km/h = 0.625 hours
Add together both times to work out how long the entire journey took
1.25 + 0.625 = 1.875 hours
Using the Speed formula from before
Speed = 100km / 1.875 =
53 1/3 km/h or 53.3 recurring km/h
