(b) Drawing the diameter of the circle
(c) Drawing perpendicular diameters
(d) Measuring the circumference of the circle

(ii) How does the baker ensure the circle is divided into equal parts?
(a) By using a ruler to measure equal distances
(b) By drawing perpendicular bisectors of the diameters
(c) By marking equal sections along the circumference
(d) By ensuring all diameters are perpendicular

(iii) Why is the perpendicular diameter significant in this construction?
(a) It divides the circle into two parts.
(b) It helps in finding the radius of the circle.
(c) It ensures the circle is divided into four equal parts initially.
(d) It measures the area of the circle.

(iv) If the baker uses the same method to divide a larger cake into 12 slices, what additional
step is required?
(a) Draw more diameters dividing the circle into 12 equal angles.
(b) Measure the circumference of the circle and divide it into 12 equal parts.
(c) Use a protractor to measure angles of 30°.
(d) Bisect the existing sections to create more slices.
