Real.circleAverage_congr_sphere

∀ {E : Type u_1} [inst : NormedAddCommGroup E] [inst_1 : NormedSpace ℝ E] {c : ℂ} {R : ℝ} {f₁ f₂ : ℂ → E},
  Set.EqOn f₁ f₂ (Metric.sphere c |R|) → Real.circleAverage f₁ c R = Real.circleAverage f₂ c R

If two functions agree on the circle, then their circle averages agree.
