The area, a, of a circle is given by a=tor, where r is the
radius of the circle. round all values to the nearest whole
number buiore substituting into the formula in order to
estimate the area of a circle with radius 11.3 centimeters.
oa) 27 cm
ob) 48 cm
oc) 70 cm
od) 363 cm?

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

the correct answer would be the third option
