semicircle=1/2pir^2 hmm is area of circle with diameter of 1/2x interesting umm the area of a semicircle with a diameter of x is (1/8)pix² the area of a circle with diameter of 1/2x is (1/4)pix² 1/8pix² is 1/2 of 1/4pix²
first blank is 1/2 or half
circle's diameter is 1/2x the radius of the seimicircle is x/2 or 1/2x the circles's diameter is the same as the radius of the semicircle
the area of the semicircle with diameter of 4 is about radius=4/2=2 1/2pi2^2=2pi or about 3.28 in²
area of circle with diameter of 2in is about 2/2=1, radus is 1 area=pi1²=pi=3.14 in²

The area of a semicircle with a diameter of x is half the area of a circle with a diameter of [tex] \frac{1}{2}x [/tex]
The circle's diameter is equal to the radius of the semicircle
The area of the semicircle is about 6.28 square inches.
The area of the circle with a diameter of 2 inches is about 3.14 square inches.
