R = 24/2 = 12 inches. WebApr 6, 2024 · The radius is approximately equal to 1.785. The precise answer is √ (10 / π). To get this result, recall the formula area = π × r2. We transform it to the form r2 = area / π, and so we see that the radius is equal to the square root of area / π. Plugging in area = 10, we obtain: radius = √ (10 / π) ≈ √ (10 / 3.14) ≈ √3.185 ≈ 1.785. fitz and the tantrums denver botanic gardens
