Answer:
35
Step-by-step explanation:
Given
n (A) = 15
n (B) = 20
Students who do not like any subject = 5
Hence, number of students who would like either both or either of the two subjects = 60-5 = 55
n (A or B) = n (A) + n (B) - n (A and B)
Number of students linking both the subjects
55 - 15-20
= 55-35 = 20
Number of students linking only one subject = 60-20-5 = 35

Answer:
Step-by-step explanation:
The perimeter of a circle is the circumference of the circle. To find it, use the formula 
.
The diameter here is two times the radius x, d = 2x. But here it has been decreased by 2 so it becomes d = 2x - 2.
Substitute into the formula.
