Answer:
31.5 squared cm
Step-by-step explanation:
Let's start with the triangle part :)
We have a base half a base of 3, so let's add 3 more to make it complete, which gives us 6.
6cm (base) x 6 cm (height) = 36 cm.
Since it's a triangle, we must divide by 2 which gives us 18 cm.
Now let's move on to the circle.
we have a radius of 3.
in order to find area of a circle, we have to do pi x r squared.
We have a radius of 3 so let's square it, which give us 9. after that we multiply 9 by pi.
In the directions, it says use 3 for pi. So we do
3 x 9 which equals 27.
But WAIT- it's a <u>half</u> circle so we <u>divide 27 by 2</u> which gives us <u>13.5 </u><u>cm.</u>
Let's add the two
<u>1</u><u>8</u><u> </u><u>cm </u><u>+</u><u> </u><u>1</u><u>3</u><u>.</u><u>5</u><u> </u><u>cm</u> <u>=</u><u> </u><u> </u><u>3</u><u>1</u><u>.</u><u>5</u><u> </u><u>cm </u><u>squared</u> <u>(</u><u>remember</u><u> </u><u>to </u><u>square </u><u>it </u><u>since </u><u>it's </u><u>area!</u><u>!</u><u>)</u>
<u>I </u><u>hope </u><u>this </u><u>helped!</u><u>!</u><u>!</u><u> </u><u><</u><u>3</u>
What would be the effect of this change is: a). both area rate and flow rate would increase.
<h3>Shifting of gear</h3>
Assuming a driver shift into third gear in which there was reduction in the engine speed while on the other hand the tractor speed increase.
The effect of the change will result in the increase in area rate as well as the flow rate.
Therefore the correct option is<em> </em>A.
