What is the area of the shaded reigon? round to the nearest hundredth.

Area of full circle = πr^2

= 3.14 * 12^2

=3.14 * 144

=452.16 cm^2

Area of rectangle = l x w

= 10 * 3

= 30 cm^2

Area of shaded region:

452.16 - 30 = 422.16 cm^2

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
