Answer:
1.341
Step-by-step explanation:
I'm smart at maths
No, it is not a valid inference because her classmates do not make up a random sample of the students in the school.
To find the diameter, divide the area(254.34) by pi(3.1415) and then square the quotient
That is the radius now just times that by 2 so 2 x 8.99 = 17.98
Now I have a felling the might be wanting 18 because 8.99 is so close to 9 and this is also true for 80.95. They probably want 80.95 = 81, which the square root of that is 9, which is the radius and if you times that by 2 the diameter would equal 18
