For the first question the answer is the second option.
For the second question the answer is the first option.
Hope I didn't mess up for your sake
You multiply 3.14 by the diameter or 2 times the radius
for area you do pi or 3.14*radius squared
Answer:
A
Step-by-step explanation:
You are right
Option B:
sin x = 1 is the equation represented by the intersection of the graph.
Solution:
The graph lies between -1 and 1 in y-axis.
x-axis of the graph is all real numbers.
The graph oscillates between -1 and 1 and a shape that repeats itself every 2π units.
That is the domain of the graph is all real numbers.
The range of the graph is [-1, 1].
It clearly shows that, it is the graph of sinx = 1.
Hence sin x = 1 is the equation represented by the intersection of the graph.
Option B is the correct answer.
