Q. Question 33\newlineNot yet answered\newlineMarked out of 11.0000\newlineFlag question\newlinekeliling setengan lingkaran dengan jari - jari 7 cm 7 \mathrm{~cm} adalah...cm\newlineA. 2222\newlineB. 3636\newlineC. 2828\newlineD. 4444
  1. Circle Circumference Formula: The formula for the circumference of a full circle is 2×π×r2 \times \pi \times r.
  2. Semicircle Circumference Formula: For a semicircle, we need to add the diameter to the half of the full circle's circumference, so the formula becomes π⋅r+2⋅r\pi \cdot r + 2 \cdot r.
  3. Radius Substitution: Plug in the radius r=7 cmr = 7\,\text{cm} into the formula: circumference = π×7+2×7\pi \times 7 + 2 \times 7.
  4. Calculation: Calculate the numerical value: circumference=22×(approx for π)+14\text{circumference} = 22 \times (\text{approx for } \pi) + 14.
