Q. A circle has a circumference of 77,850850 units.\newlineWhat is the radius of the circle? Use 33.1414 for π \pi and enter your answer as a decimal.\newline\square units
  1. Circle Circumference Formula: The formula for the circumference of a circle is C=2×π×rC = 2 \times \pi \times r, where CC is the circumference and rr is the radius.
  2. Given Values and Formula: Given C=7,850C = 7,850 units and π=3.14\pi = 3.14, we can solve for rr by rearranging the formula: r=C2π.r = \frac{C}{2 \cdot \pi}.
  3. Plug in Values: Plug in the values: r=7,8502×3.14.r = \frac{7,850}{2 \times 3.14}.
  4. Calculate Radius: Calculate the radius: r=7,8506.28r = \frac{7,850}{6.28}.
  5. Division Calculation: Perform the division: r1,250r \approx 1,250.
