Answer:448.5
Step-by-step explanation: first you have to see what 50% of 299 is so you do 299/2=149.5 so now they are marking it up so you do 299+149.5 =448.5
The circumference of a circle is pi x 2 x radius.
To find the radius, divide the circumference by pi, then divide that by 2:
36/3.142 = 11.4576703
Radius = 11.4576703/2 = 5.7288
Rounded to one decimal place the radius is 5.7 units.
