Answer:
Step-by-step explanation:
Step 1 - As both triangles have lengths the same size, they both add together to equal a rectangle. Therefore:
4 x 3 = 12
Which is the area of the triangles.
Step 2 - Calculating the area of a circle uses the formula:
Where r is the radius of the circle.
Plug the known variables in:
However, this is the area of a full circle. The figure is only half a circle so we must divide this by two:
28.26 ÷ 2 = 14.13
Now, add the area of the semi-circle to the area of the triangles:
14.13 + 12 = 26.13
Therefore, the area of the figure is .
Hope this helps!
Answer:
Step-by-step explanation:
divide y by x
in a table and coordinate pair, which is something like (0,4), x always comes first. So, in this table x is the time in seconds and y is the distance in meters. 120/4=30 meters per second. For the second part of the table, since we know what the slope is, or the constant rate of change, 30, we can multiply 30 by 25 which is 750. You can also use the equation y=mx, m is the slope, and x is a point on the coordinate pair. For example, in the second table, y=30(25). For the last part of the table, you can use the same equation. 270=30x. We try to get x alone so we do, 270 divided by 30 which is 9. So a cheetah runs at 270 meters per 9 seconds.
You need to specify the statement needed to use the equation. Thank you. I will then answer it if needed.
