Question

Work out the area of this circle take (pi) to be 3.142 and give your answers to 2 decimal places

Answer 1

A = 63.63 m^2

Explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

r = d/2 = 9/2 = 4.5

A = 3.142 * (4.5)^2

A =63.6255 m^2

Rounding to 2 decimal places

A = 63.63 m^2
