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.

Answer:

4 + 9x² + 1x³ + 12x⁵

Step-by-step explanation:

3x² + 6x² = (3 + 6)x² = 9x²

4 + 3x² + 8x³ + (-7x³ + 12x⁵ +6x²) = 4 + <u>3x² + 6x² </u> + <u>8x³ - 7x³ </u> + 12x⁵

                                                    = 4 + 9x² + 1x³ + 12x⁵
