A map of a public park shows a circular pond. There is a bridge along a diameter of the pond that is 0.55 mi long. You walk across the bridge, while your friend walks halfway around the pond to meet you at the other side of the bridge. How much farther does your friend walk? Round your answer to the nearest hundredth. Use 3.14 for straight pi.

The circumference of a circle is pi times diameter, so half-way around the pond is (1/2)pi times diameter.

The difference between walking around the pond and walking across the bridge is: 1.57d - d = 0.57d

Plug in diameter of 0.25

0.25*0.57 = 0.14 miles

Step-by-step explanation:

0.14 mi

Step-by-step explanation:

find the circumference of the pond and then divide by 2 since they only walk halfway around the pond

subtract the distance your friends walked and the distance you walked to find how much further your friends walked

RESULT

0.14 mi

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
