To find the circumference of a circle, you can use the formula:
\[ C = \pi \times d \]
where \( C \) is the circumference and \( d \) is the diameter of the circle. You can also use the radius \( r \) in the formula:
\[ C = 2 \pi r \]
Since you provided the diameters directly, we will use the first formula. Using \( \pi \approx 3.14 \), we can calculate the circumference for each circle.
-
For a circle with diameter 7 ft: \[ C = \pi \times 7 \approx 3.14 \times 7 \approx 21.98 \text{ ft} \approx 22.0 \text{ ft} \]
-
For a circle with diameter 44 ft: \[ C = \pi \times 44 \approx 3.14 \times 44 \approx 138.16 \text{ ft} \approx 138.2 \text{ ft} \]
-
For a circle with diameter 49 ft: \[ C = \pi \times 49 \approx 3.14 \times 49 \approx 153.86 \text{ ft} \approx 153.9 \text{ ft} \]
-
For a circle with diameter 48.4 ft: \[ C = \pi \times 48.4 \approx 3.14 \times 48.4 \approx 152.34 \text{ ft} \approx 152.3 \text{ ft} \]
-
For a circle with diameter 16.6 ft: \[ C = \pi \times 16.6 \approx 3.14 \times 16.6 \approx 52.20 \text{ ft} \approx 52.2 \text{ ft} \]
