C. None of the above.

The correct answer would be -e/f. Remember that fractions are really just division problems and if you divide a negative by a negative the result will be a positive. A helpful trick is to just count the negative signs, if there are an even number the result will be positive, if there are an odd number the result will be negative.

The distance around a water fountain is 150 inches.What is the distance from the edge of the fountain to the center?
Scrat [10]

The distance from the edge of the fountain to the centre is approximately 23.87 inches.

The water fountain forms a circle. The distance around the water fountain is the circumference of the circle formed.

Therefore,

circumference = 2πr

150 = 2πr

The distance from the edge of the fountain to the centre is the radius of the circle formed. Therefore,

75 = πr

r = 75 / 3.14159

r = 23.8732616287

r = 23.87 inches

The distance from the edge of the fountain to the centre is approximately 23.87 inches.
