8. Sydney drew a scale diagram of a Circular fire pit in the centre of a circular patio with an actual circumference of 15 m. The circle containing the fire pit is a reduction of the circular patio by a scale factor of 1/3 (circumference = pi x diameter)
a. determines the diameter of the actual fire pit, to the nearest hundredth of a metre.
B. What is the diameter of the fire pit in the scale diagram if the scale factor used was 2/15?
C. after construction, the raised fire pit will have a surface area of 6.14 m² what will the surface area of a similar fire pit that is in large by scale factor of 3.
D. After construction, the rays fire pit will have a volume of 0.99 m³. If the volume of the enlargement is 26.73 m³, what scale factor was used?

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
