Answer:
12
Step-by-step explanation:
Three cars each need 4 wheels, so that is...
4 + 4 + 4 wheels, which is 12 wheels
Answer:
All Triangles are closed figure polygons that have three straight sides
Step-by-step explanation:
All 2D shapes are plane figures so this one is false. Three right angles are greater than 180 so this is fake. Polygon and closed figures are shapes with three or more closed sides. And triangles have straight sides.
Answer:
I don't see the file with it
Step-by-step explanation:
First of all we can draw a parallel line to divide the figure into a triangle and a rectangle as shown in the figure. To find the area of our rectangle, remember that the area of a rectangle is length times width, so

. Since we know for our figure that the length and width of our rectangle are 13cm and 6cm respectively, lets replace those values in our formula to get its area:


Similarly, the area of a triangle is one half times base times height, so

. Since we know that our base is 8cm and our height 6cm, lets replace those values in our equation to find the area of our triangle:


Now the only thing left is add our areas:

We can conclude that the correct answer is <span>

Answer:
452.16cm squared
Step-by-step explanation:
Area for a circle formula is A = pi * r^2
Area = 3.14 * 12^2
Area = 452.16
