One-quarter of a circular pizza of diameter 28 cm was removed from the whole pizza. What is the perimeter (in cm) of the remaining pizza? (Take $\pi = \frac{22}{7}$)
Answer & explanation
Correct answer: option 2
We know that,
Circumference of circle = πd
Diameter of pizza = 28cm
Total circumference of pizza = \(\frac{22}{7}\)× 28 = 88cm
Circumference of \(\frac{3}{4}\)of pizza = 88 × \(\frac{3}{4}\)= 66cm
Perimeter of remaining pizza = 66 + 14 + 14 = 94
