Answer:
226.8cm^2
Step-by-step explanation:
A=pir^2
24/4 = 6 (radius of small circles)
pi6^2= 113.097335529 times 2 (because theres 2 of them)
=226.8
24/2 = 12 (radius of big circle)
pi12^2= 452.4 minus 226.8 (to get the leftover space)
=226.8
Answer:
The result is significant.
Step-by-step explanation:
Here,
p = 30 ÷ 330 = 0.091
thus, q = 1 - p = 0.909
Also, 
⇒ 
The z-score is:


Thus, at 95% confidence interval, p-value = 0.005
The result is significant at p < .05.
