To determine which chart is correctly developed with the circumference and area of a circle with a radius of 5 cm, we can use the formulas for circumference and area of a circle:
- Circumference (C): \( C = 2\pi r \)
- Area (A): \( A = \pi r^2 \)
Given \( r = 5 \) cm:
-
Circumference: \[ C = 2 \pi (5) \approx 2 \times 3.14 \times 5 = 31.4 \text{ cm} \]
-
Area: \[ A = \pi (5^2) = \pi (25) \approx 3.14 \times 25 = 78.5 \text{ cm}^2 \]
Thus, the correct values for a circle with a radius of 5 cm are:
- Circumference: 31.4 cm
- Area: 78.5 cm²
From the options provided, we find the correct one is:
Radius Circumference Area
5 cm 31.4 cm 78.5 cm²
This accurately represents the calculations for the circumference and area of the circle with a radius of 5 cm.
