Answer:
Hello the answer is
diameter = 49cm;
radius = diameter/2 = 24.5cm;
circumference = 2πr ≈ 153.94 = 154cm
1 revolution = 154cm
50 revolution = 7700cm = 77m
I hope I am correct. also please mark brainliest
Step-by-step explanation:
The circumference of a circle is always calculated by 2

R
So if R=2.5 m this circumference is 2*

*2.5 m
Which is 5

m (choice B)
Hope this helped!
1 hour because you are traveling 80 miles per hour.
The correct answer is B)y=2x-6
2x-2 must be zero or greater, since we cannot have a negative quantity under the radical sign (unless we allow for imaginary roots).
Solving 2x-2≥0, we get x-1≥0, or x≥1. x must be equal to or greater than 1.
16 - 16, so the answer to the 2nd problem is the fourth one: x=4.
