Answer: 4. 432 cm^2/2 = 216 cm^2
6. 309.76 mm^2
8. pi * 22^2 = 484pi (or, approximately 1,519.76) in^2
484/2 = 242pi or 759.88 in^2.
10. 297.84 in^2/2 = 148.92 in^2
Step-by-step explanation:
To find the area of a triangle, you take the base and multiply by the height, and then divide by 2. Hence giving me the answers I obtained in #4 and #10.
A square is equal on all sides, so you would just square the measurement of the one side.
To find the area of a circle, you would do pi times the radius^2. Since this is a semicircle, you actually should divide the number you got by 2. (Which is why I did so up above).
Answer:
its option 2 because the y values don't repeat
Step-by-step explanation:
Answer:
1 3/4
Step-by-step explanation:
Area = 23.5279 m
Perimeter = 21.92 m
Round as needed.
Your teacher might want you to round to round before the math because it says it’s an ESTIMATE in which case
Area = 24 m
Perimeter = 22 m
8.03 x 2.93 = 23.5279
2 x 8.03 + 2 x 2.93 = 21.92
