Answer:
7 R -14
Step-by-step explanation:
Answer:
Approximately 201 squared inches.
Step-by-step explanation:
So, the composite figure is made up of a square and a semi-circle. The square has side lengths of 12 and the semi-circle has a radius of 6.
The total area of the figure would be the area of the square plus the area of the semi-circle. Thus, find the area of each individual figure.
Square:
The area of a square is given by:

Where l is the side length.
Substitute 12 for l:

So the square is 144 square inches.
Semi-circle:
The area of a semi-circle is given by:

Substitute 6 for r and 3.14 for π:

Therefore, the total area is:

To answer the problem above, we first find the velocity of the train that is travelling. It is calculated as follows:
Velocity = 42 km / 15 min = 2.8 km / min
The distance traveled after 3 hours at this speed is calculated by multiplying the velocity and the number of hours.
Distance = <span>2.8 km / min ( 3 hours ) ( 60 min / 1 hour ) = 504 km</span>
