Radius Circumference Area

279in. _____in ___ in 2

1 answer

To find the circumference and area of a circle with a radius of 279 inches, we can use the following formulas:

  1. Circumference (C) = 2 * π * r
  2. 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
