Answer:
6.4π units.
Step-by-step explanation:
Length of the arc = radius * the angle in radians
= 4 * 288 * π / 180
= 6.4π.
10*10*10*10*10*7867 equal 786700100
Answer:
The width is 7 inches and the length is 9 inches
Step-by-step explanation:
So we can divide 32 by 2 because we know perimeter is 2(l*w)
So it becomes 16, and it is now (l*w)
We know that the length is 2 inches longer so we subtract 2 from 16.
It then becomes 14 inches so therefore we can then divide it by 2.
14 divided by 2 is 7 and therefore we add 2 because we subtracted the two from earlier temporarily.
Therefore the width is 7 and the length is 9.
Surface area is the area of all the surfaces, that's why it's called surface area...so let's calculate the area of the bottom rectangle, the front rectangle, back rectangle, and the two triangles on the sides.
Bottom Rectangle:

Length = 12 yd, Width = 9 yd


Front Rectangle:

Length = 12 yd, Width = 5 yd


Back Rectangle:

Length = 12 yd, Width = 8 yd


Triangle:

Base = 9 yd, Height = 4 yd


Remember we have two of these triangles.
Now let's add up all the measurements:
