hello :
the circumference of a semicircle : 2πr/2 =πr
p/2 = <span>πr =3.14(6) =18.8 cm
</span>
Answer:.
Step-by-step explanation:
<span>let length of painting = L
and width = W
from area = length times width
180 inch^2 = L times W
but L = 5/4 times W
180 inch^2 = 5/4 times W times W
W^2 = (4 x 180)/5
W = 12
but L = 5/4 x W
L = 5/4 x 12
L = 15
</span>
<span>Answer: The dimensions of the painting are </span><u>12 x 15 inches</u>.
Well when you multiply it would most likely be 180
