a = 17.9 meters^2
Given that:
• circumference of circle = 15 meters
T= 3.14
As we know that:
• circumference of circle = 2 nr
By putting values:
•15 = 2 (3.14) r
By simplifying:
• 15=6.28r
Dividing both sides by 6.28 we get:
• r= 2.39 meters
Now for finding area:
• Area = 1 r2
Putting values:
• Area = (3.14) (2.39)*2
By simplifying we get:
• Area = 17 .935 meters’2
So by rounding off radius to nearest tenth:
• radius =r=2.4 meters
Rounding off area to nearest tenth:
• area =a = 17.9 meters’2
Why y equals 2 is Function
Answer: In general, a relationship f(x) =y is a function only if, for each value of x that you plug into it, you get only one value for y.
