1 answer:
To answer this question you will set up the proportion shown in the attached picture.
There are 2 ways to solve this.
1. You can create an equivalent ratio by determining the factor that will take you from 1 cm to 2 cm and apply his factor to the 19 miles.
The answer would be 19 x 2= 38 miles for 2 centimeters.
2. The second strategy is to use cross products to get an answer. You multiply the number diagonal from each other. See picture for this work.

Initial speed of the skateboard (u) = 0 m/s (Starts from rest)
Acceleration of the skateboard (a) = 2 m/s²
Time taken by the skateboard (t) = 2s
By using equation of motion, we get:
Final speed of the skateboard(v) = 4 m/s

I cannot see which region is shaded so I will solve for both:
1.
the radius of one circle is 3:
A=
A=(3.14)(9)
A=(28.26)
The area of the three circles is 84.78 feet squared
Area of rectangle is 108 feet squared (16*8)
108-84.78=23.22
The area of the shape around the circles is 23.22 feet squared
