Answer:
see below
Step-by-step explanation:
For the first question, you should multiply the scale dimension by 30 to get the actual dimension. This is because the scale is 1:30 where the scale dimension is the 1 and the actual dimension is 30, so therefore, the scale dimension is 1/30th of the actual dimension, so to get the actual dimension, we can multiply the scale dimension by 30. I'm not totally sure how to attach pictures from my phone on my computer (sorry) but an example of a drawing could be two rectangles, the first (this is the scale drawing) having dimensions of 1 by 2 units and the second (this is the actual drawing) having dimensions of 30 by 60 units. I hope this helps!

Step-by-step explanation:
Area of a circle is: 
'r' is the radius.
We are given the diameter of 6ft. Since the diameter is twice the radius, the radius is 3 ft.
6/2 = 3
Using 3.14 for pi:
The area of the circle should be 28.26 square feet.
First person = 10 min
Second person = 15 min
Time together = x
Equation Formation
x = (10+15) ÷2
x = 12.5
Answer = 12.5 minutes
