You could solve this mathematically but i mean you could use your eyes.... Its most likely C
;)
For the perimeter you have to consider the EXTERNAL SHAPE ONLY:
a) the perimeter of half a circle WITHOUT ITS DIAMETER is:
π.R - 2R → 3.14x1.5 - 2x1.5 → 1.71 cm
b) the perimeter of the rectangle WITHOUT THE UPPER SIDE is:
2.5+3+2.5 = 8 cm
Hence the perimeter of the figure is 1.71 + 8 = 9.71 cm
2) Area of the figure:
Area of half circle is π.R²/2 →3.14 x (1.5)²/2 → Area half circle = 3.5325 cm²
Area of rectangle = 2.5 x 3 = 7.5 cm²
Total area = 3.5325 + 7.5 = 11.0325 ≈ 11 cm²
Answer:
5400
Step-by-step explanation:
look at the photo it shows the problems that
There are 3 egg rolls divide evenly to 8 sisters
for 1 egg roll each sister would receive 1/8 since there are 3 egg rolls
multiply 1/8 x 3
each sister will get 3/8 of an egg roll
hope this helps
= 8
