this figure is 14 of a circle.

what is the best approximation for the perimeter of the figure?

use 3.14 to approximate pi.

a.7.85 in.
b.12.9 in.
c. 17.9 in.
d. 31.4 in.

the file is the picture of the quarter or 1/4 circle

C. 17.9

Step-by-step explanation:

Formula: 1/4 π x d

d = diameter

d = 2r

1/4 π  x  10 = 10/4 π

Add the 2 non-curve sides

5 + 5 = 10

10/4  x  (3.14 = π)  x  10

= 17.9

I hope this helps! :)

what is the answer to this

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
