Find the circumference of the circle. Write the answers in terms of pi as well as using 3.14 as pi.
C = da
Circumference in terms of pi?
5 in
Circumference using 3.14 as pi?
Students, draw anywhere on this slide!

Step-by-step explanation:

Given

The radius of the circle = r = 5 in

We know that diameter is twice the radius.

so d = 2r = 2(5) = 10 in

Finding the circumference of the circle in terms of pi

Using the formula to find the circumference of the circle

C = dπ

C = 10×π

C = 10π inches

Thus, the circumference of the circle in term of pi = 10π inches

Finding the circumference of the circle using π = 3.14

We know that the formula to find the circumference of the circle

C = dπ

Given

π = 3.14

substituting π = 3.14 to find the circumference of the circle

C = 10×3.14

C = 31.4 inches

Thus, the circumference of the circle = 31.4 inches

1.  The ratio is 6:14 or 6/14,  3:7 or 3/7.

2. 2/8 or 1 out of 4.

4. At approximately  16c

a cup, Folgers Coffee is better value than Seattle's Best which costs  18c a cup.

Step-by-step explanation:

1. Talley, ratios work like fractions. The ratio is 6:14 or 6/14, which reduces to 3:7 or 3/7.

2. If 8 out of 10 prefer Crest, then 2 out of 10 do not.  The ratio of those who  do not prefer Crest (2) to those that do prefer Crest (8) is 2/8 or 1 out of 4.

4. To find the respective value per cup, divide the prices give by the number of cups they represent. We shall represent Folgers Coffee by  f and Seattle's Best by  s

.

f = 12.88/80

= 0.161

Folgers Coffee is approximately  16

c per cup.

s = 9.00/50

s = 0.18

I dont have room so i'll put it in the comments
