First one.
tan(pi/2) is the asymptote, and 2pi/4*x = pi/2*x, between 0<x<2, goes from 0 to pi, so it only passes thru pi/2.

Step-by-step explanation:
<u>GIVEN :-</u>
- Diameter of half circle = 8cm
<u>TO FIND :-</u>
- Circumference of half circle
<u>FACTS TO KNOW BEFORE SOLVING :-</u>
Circumference of a circle with radius 'r' is = 
⇒ Circumference of half-circle with radius 'r' = 
<u>SOLUTION :-</u>
Radius = 
So , Circumference of half-circle =
cm
Answer:
There were 18 1 point goals and 40 2 point goals
Step-by-step explanation:
Let the number of one point shots be x and the number of two point shots be y
Total number of shot is 58
x + y = 58 ••••(i)
Then;
Total of 1 point is 1 * x = x
Total of 2 points is 2 * y = 2y
x + 2y = 98 ••••••(ii)
x = 98-2y
Put this in 1
98-2y + y = 58
-y = 58-98
y = 40
x = 58-40
x = 18
