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>

the answer is 6 i think
Step-by-step explanation:
Answer:
x = 1 . 14
Step-by-step explanation:
5x + 7 + 2x + 1
5x + 2x + 7 + 1
= 7x + 8
= x = 8 / 7
x = 1.1 4
Hope this answer helps you :)
Have a great day

Answer:
Step-by-step explanation:
1 = (20 x 70) + (70 x 20) = 1400 x 2 = 2800 squared meters
2 = 9.18 x 2 = 18.36 + 9.72 = 28.08 squared centimeters
3 = 9 x 4 = 36 + 6 + 3 = 45 squared units
Answer:
See explanation
Step-by-step explanation:
Assuming the given equation is
To solve for r, we first divide both sides by a.
We now subtract 5 from both sides:
We now divide through by - 1 to get:
Or
