Find the circumference of the circle with the given radius or diameter. (Use 3.14 for it) r=20

C = 2πr = 2 * 3.14 * 20 = 125.6

Step-by-step explanation:

The formula of a circumference of a circle:

d - diameter

r - radius

We have the radius r = 20.

Substitute:

use π ≈ 3.14

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
