Answer:
total area = 18.28 in.^2
perimeter = 16.28 cm
Step-by-step explanation:
Area:
The total area of the figure is the sim of the area of the rectangle and the area of the semicircle.
total area = LW + (1/2)(pi)r^2
total area = (4 in.)(3 in.) + (1/2)(3.14)(2 in.)^2
total area = 12 in.^2 + 6.28 in.^2
total area = 18.28 in.^2
Perimeter:
The perimeter of the figure is the sum of the lengths of the left side, bottom side, and right side of the rectangle and the circumference of the half circle.
perimeter = 3 cm + 4 cm + 3 cm + (1/2)(pi)d
perimeter = 10 + (1/2)(3.14)(4 cm)
perimeter = 10 + 6.28 cm
perimeter = 16.28 cm
Answer:
12960 biscuits
Step-by-step explanation:
1 carton= 24 packets of biscuits
45 cartons= 45x24=1080 packets.
One packet = 12 biscuits
1080 packets- (1080x12)
=12960 biscuits

Answer:
Step-by-step explanation:
5/9 = 2,500/4,500
to get that you times 5 by 500
and 9 by 500
"I am a figure with six layers .each of my layers is the same."---> using this sentences, you can conclude that the shape is cube because cube made of 6 similar square.
<span>my bottom layer has a perimeter of 28 units ---> Using this sentences, you can know the square perimeter is 28. Then the square side would be:
square perimeter= 4* side
28= 4* sides
side= 7
Then, the volume of the cube would be:
cube volume= side^3
cube volume= 7^3= 343 cubic units
I think there is a typo somewhere in this question. The calculation should be true, but it is not in 200-300 range. The volume that in 200-300 would be when the side is 6 unit(volume=216), but the perimeter should be 24 not 28.
If the perimeter 28, volume= </span>343 <span>
If the perimeter 24, volume= 216</span>
