Answer:
the second one
Step-by-step explanation:
this is the proper way of wrting
1)
Lateral area is the surface area, minus the bases. The area of a square is base times height. The lateral area is 112 centimeters squared, and the surface area is 336 centimeters squared.
2)
The bases of prisms are the triangles. The lateral area of the prism is 695 meters squared. The area of a triangle is base times height divided by 2. The surface area of the prism is 727 meters squared.
3)
The area of a circle is pir^2. The surface area of the cylinder is 1,230 inches cubed.
4)
The area of the pyramid is 790.
5)
The answer to number 5 is 2,254.
6)
The last answer is 21.7 centimeters. but I'm not like 100% sure.
1800 cm: 20 m in its simplest form is 9cm : 10 cm
<h3>What is ratio?</h3>
Ratio says how much of one thing there is compared to another thing. Ratio compares value.
Therefore, let's make the unit the same.
0.01 m = 1 cm
20m =
length = 20 / 0.01
length = 2000 cm
Therefore, the ratio is as follows:
1800 cm : 2000 cm
Let's write it in it simplest form.
1800 / 2000 = 9 / 10
Therefore, the simplest form is 9 cm : 10 cm
