use the formula 2πr
- 106.76
- 300.96
- 2×3.14×(1/2)×39 = 122.46
- 78.5
the c bit I did the whole process cuz the diameter is given and for the d bit i thought what you were trying to say is 25 diameter.

Answer:
false
Step-by-step explanation:
A graphing calculator shows the vertical scale factor is -5, so the equation is ...
y = -5(x +1)² + 2
Then the x-intercepts are
0 = -5(x +1)² + 2
(x +1)² = 2/5
x +1 = ±√(2/5)
x = -1 ±√(2/5) ≈ {-1.63245553203, -0.36754446797}
