The complete question is,
Work out the area of a circle. Take (pie) as 3.142 and give your answer to 2 decimal places. the diameter is 9 m.
Given,
Diameter of the circle = d = 9 m
pie = 3.142
Area of circle = πr²
as we know that, radius is half the diameter, so we have, r = d/2
Area of circle = π (d/2)²
= 3.142 × (9 / 2)²
= 3.142 × 81 / 4
= 63.62 m²
Therefore, the area of the circle is 63.62 m²
