Answer: The expression simplified is 14.9d+3.6h-17.
Step-by-step explanation:
Answer:
19,27 cm^2
Step-by-step explanation:
area of triangle = (6 x 3)/ 2 = 9 cm^2
circle area : 3^2 x 3,14 = 28,27 cm^2
area of shaped region = 28,27 - 9 = 19,27 cm^2
so you take the average of the x coordinates and the average of the y coordinates to get the midpoint like this
