Answer:
112.5 pi
Step-by-step explanation:
hi, to find this we need to know the formula for the area of a circle. it is:
a=pi*radius^2
so the radius is 30/2=15
now we can just plug 15 in to find the area.
a=pi*15^2
a=225pi
now, that is the area for the full circle, but here it is a semi circle, so we just divide 225 pi by 2 to get
112.5 pi, or 112.5π
