The perimeter of the given circle is 25.1 square cm.

Step-by-step explanation:

  • From the given diagram, the radius of the given circle is 4 cm.
  • The perimeter of any given circle is calculated by multiplying 2π with the radius. The radius of this circle is 4 cm and it says π = 3.142
  • The Perimeter for the given circle = 2π × r = 2 × 3.142 × 4 cm = 6.284 × 4 cm = 25.136 cm.                                                       Rounding this off to one decimal 25.136 square cm, the perimeter equals 25.1 square cm.

Molly must drive across a bridge over a river eight times each week. Because the bridge is narrow and traffic is congested, Moll
oee [108]

Based on Molly's willingness to pay for the 8th trip, and the number of trips she can make over the bridge, her willingness to pay for the bridge repair would be<u> $1.00.</u>

<h3>What is Molly's willingness to pay for taxes to fix the bridge?</h3><h3 />

Molly's willingness to pay for trips is equal to the total consumer surplus she gets.

This means that her consumer surplus is $0.50.

With the bridge fixed, she can make 2 more trips than before because she can make 10 trips.

Her willingnesss to pay for the taxes will therefore be equal to her willingness to pay for the remaining trips:

= 0.50 x 2

= $1.00
