My name is Ann [436]3 years ago

Answer:

Step-by-step explanation:

Recall that the formula for the area of a rectangle of length L and width W is

A = LW.  

What if the area is 19 cm^2 and the length is 38 cm?  Solving the above equation for W, we get

W = A/L

and if we let A = 19 cm^2 and L = 38 cm, then W would be W = (19 cm^2) ? (38 cm) = (1/2) cm.  The rectangle would be very narrow, but certainly possible.

Answer:

  2πr cm

Step-by-step explanation:

The circumference of a circle of radius r is ...

  C = 2πr

For a radius of (r cm), the circumference is ...

  A = 2π(r cm) = 2πr cm

For a radius of (2r cm), the circumference is ...

  B = 2π(2r cm) = 4πr cm

Then the difference between the circumferences is ...

  B -A = (4πr cm) -(2πr cm) = 2πr cm . . . . difference in circumference
