To find the circumference and area of a circle with a radius of 279 inches, we can use the following formulas:
- Circumference (C) = 2 * π * r
- Area (A) = π * r²
Substituting 3.14 for π and 279 for r:
Circumference Calculation:
\[ C = 2 * 3.14 * 279 \] \[ C = 6.28 * 279 \] \[ C = 1757.32 , \text{in} \]
Area Calculation:
\[ A = 3.14 * (279^2) \] \[ A = 3.14 * 77841 \] (since \( 279^2 = 77841 \)) \[ A = 243,249.34 , \text{in}^2 \]
Now we can complete the table:
| Radius | Circumference | Area | |----------|---------------|-------------| | 279 in | 1757.32 in | 243249.34 in² |
So the completed table is:
- Circumference: 1757.32 inches
- Area: 243249.34 square inches
