Answer:
351π cm^2.
Step-by-step explanation:
Area of shaded part = area of the large circle - area os small circle
= π * (13+7)^2 - π * 7^2
= 400π - 49π
= 351π.
IO/2.4 = I5/x
IOx = 36
x = 3.6
<span>The best way is to find the areas of the bases and the lateral faces separately and add them.
Let's start:
Base area = 14 x 4 = 56
Area of rectangle = 6 x 14 = 84
Area of second rectangle = 8 x 14 = 112
Area of slanted rectangle = 4.47 x 14 = 62.58
Now there are two sides remaining which includes triangles. Seperate the triangles from them and you will be left with 2 small rectangles on the front and back and also two triangles.
Area of two small rectangles = 2( 4 x 6) = 48
Area of two triangles = 4 x 2 = 8
Now add them all,
we get ====> 370.58 Square units</span>
well lets see here
Part 1:
the full rotation will have a perimeter of 1
so we can then determine the distance from the big gear how much the smaller gear will move
smaller gear=the disance of: 1* (22/7)*2*2
If the distance converted into degrees, then:
gear A rotation= gear A distance/ gear A perimeter * 360°
gear A rotation= (22/7) * 2 *2/ {(22/7) * 8 *8} * 360°
gear A rotation= (1/16) * 360°= 22.5 degrees
Part 2:
The problem is similar to part 1 but the number is reversed.
bigger gear= 1 * (22/7) * 8 *8
bigger gear= (22/7) * 8 *8/ {(22/7) * 2 *2} = 16 rotation
hope i could help u
Almost positive this answer is the amount of hours she would work. because if she worked more hours her outcome would be a larger paycheck and if she worked less hours her paycheck would be smaller.
