Answer:
1/4 =h
Step-by-step explanation:
1.5(2-4h)=6h
Distribute
3 -6h = 6h
Add 6h to each side
3-6h+6h = 6h+6h
3 = 12h
Divide by 12
3/12 = 12h/12
81
The area of a square is its side length squared so 9^2 is 81
Circumference of the circle:
<u>The length of the 75° arc:</u>
30.3
First we find the area of the trapezoid. The formula for that is (b1+b2)/2(h)
2+10=12
12/2=6
6x4=24
To find the area of a semicircle we do πr²/2
2^2=4
4x3.14=12.56
12.56/2=6.28
24+6.28=30.28
That is extremely close to 30.3 so the paper must be a bit off.
The lcm is 84
3: 3,6,9,12,15,18,21,24,27,30,33,36,39,41,44,47.........84
4: 4,8,12,16,20,24,28,32,36,40,44........84
