To calculate the circumference and area of a circle, we can use the following formulas:
-
Circumference (C) of a circle is given by the formula: \[ C = 2 \pi r \] where \( r \) is the radius.
-
Area (A) of a circle is given by the formula: \[ A = \pi r^2 \]
Given that the radius \( r = 279 \) inches and using \( \pi \approx 3.14 \):
Circumference Calculation:
\[ C = 2 \times 3.14 \times 279 \] \[ C = 6.28 \times 279 \] \[ C \approx 1757.32 \text{ inches} \]
Area Calculation:
\[ A = 3.14 \times (279)^2 \] Calculating \( (279)^2 \): \[ (279)^2 = 77841 \] Now substitute it back into the area formula: \[ A = 3.14 \times 77841 \] \[ A \approx 245,014.34 \text{ square inches} \]
Summary:
Here is the completed table:
| Measurement | Value | |---------------------------|----------------| | Circumference (inches) | 1757.32 | | Area (square inches) | 245,014.34 |
