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
