86 Naira; divide 1075 by 12.5 (hopefully this is correct!)
Answer:
C
Step-by-step explanation:
a=
r^2
To find the radius, divide the diameter by 2
r=d/2
r=10/2
r=5
a=
r^2
a=
5^2
a=25
So, choice C is correct
Hope this helps! :)
Since we are given that the student has a brand Y phone, they are one of a sample of only 580 students. Since 80 of those students also own a brand X (they own both) the probability that the random student is one of those is 50/580 = 5/58 = 8.62%
