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

Answer:
3π units
Step-by-step explanation:
The full circumference of a circle with radius 2 is ...
C = 2πr
C = 2π(2) = 4π
The arc shown is 3/4 of the full circle circumference so is ...
3/4C = (3/4)(4π) = 3π . . . units
