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 $\pi = \frac{22}{7}$)

94

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
