What is the area of a circle with a diameter of 30m?

Answer 1

A(cic) = pi r^(2)

Where 'r' is the radius.

NB The diameter is two radii long .

So with a diameter of 30 meters , the radius is 15 m.

pi = 3.141592....

Substituting

A = pi 15m^(2)

Hence

A = 3.141592... 225 m^(2)

A = 706.858... m^(2) .

Answer 2

The formula for area of a circle is Pi x r (squared), A = Pi(rxr). So since the diameter is 30 you divide it by two and get 15 and then square it and multiply it by pi and get 706.86 meters.

Answer 3

706.86
