Answer:
okay so you would make a line straight across the middle of the spherical shape. The line that goes all the way across is the diameter. If you were to cut that line in half that would be the radius.
Step-by-step explanation:
The first circle shown in the picture provided would be an example of diameter, and the second circle would be an example of the radius. You could just make up a value, for example say the diameter is 10, the radius would be 5.

We know that:
perimeter = (2 x width) + (2 x length)
Plugging in what we know to this equation:
40 = (2 x 8) + (2 x length)
40 = 16 <span>+ (2 x length)
</span>24 = <span>2 x length
</span>12 = length
The length of the room is 12 feet
