Answer:
Check below
Step-by-step explanation:
1) Check the rectangle below with a line k, the axis of rotation in the center of the figure.
2) Since it has a perimeter of 32 units and it is to be rotated about the line, the solid to be created it is a cylinder. As you can see below.
3) Let's calculate its radius, based on the information given, i.e. the perimeter:
Since the line of rotation is the center, and the radius is half the line segment of the basis, then the radius is 5.
We know that
<span>An asphalt driveway </span>has the shape of a rectangle
so
area of rectangle=long*wide
area=21*10.5-----> 220.5 ft²
the answer is
220.5 ft²
4 yards x 36inches = 144
144/15inches=9.6
So the maximum is 9 ribbons with a little material left over.
