Use the formula A=pi*r^2

Area=56.25*pi m or 225/4*pi m or approximately 176.7 m

Explanation:

The formula for the area of a circle is A=pi*r^2, where A is the area and r is the radius

The radius if half the diameter, so

r=1/2*d

r=1/2*15m

r=7.5m

Therefore,

A=pi*r^2

A=pi*(7.5)^2

A=56.25*pi m or A~~176.7 m (correct to 1 decimal place)
