To find the area, move each semicircle to fill up the square, you'll see there are three squares, each with an area of 4*4=16, so the total area is 3*16=48
Now the perimeter:
the perimeter of a circle is π times the diameter.
perimeter of each semicircle: (1/2)π*4=2π
there are altogether 6 arches and two straight sides, so the total is
2π*6+4*2=12π+8
the area is 48 square units, the perimeter is 12π+8 units.
anything multiplied by one is itself, anything multiplied by zero is zero
Answer:
Step-by-step explanation:
there are 36 squares
red takes 1 of 4 so red has 9
blue takes 1 of 3 so blue has 12
5 of 12 of the grid is yellow
3 thousands devided by 10= 3 hundreds= (300)
Down and maximum I think I know down is right for sure but I’m not sure about the other one
