in this case we know the circumference of a circle, and we need to find out the diameter.
let's remember
the radius of a circle can be defined as
also
Step1
replace the value of the circumference of tyler's bike in equation 2 and isolate radius to find radius
Step 2
now, replace the value of radius into equation 1 to find diameter
radius=11.46 in
so, the diameter is 22.92 inches

Answer:
7. d. l = 6.48 cm, w = 6.48 cm
8. d. square
Step-by-step explanation:
For a given area, the perimeter can always be shortened by reducing the length of the long side and increasing the length of the short side. When you get to the point where you can't do that, then you have the minimum perimeter. You will reach that point when the sides are the same length: the rectangle is a square.
__
7. In light of the above, the best dimensions are √42 ≈ 6.48 cm for length and width.
__
8. In light of the above, the shape is a square.
_____
The attached graph shows the length of one side (x) and the associated perimeter. The other side is 42/x, which will also be 6.48.
