Answer:
51.1 ≈ r
Step-by-step explanation:
"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.
C = 2· π· r
What is the radius of the wheel ?
321 = 2· π· r, divide both sides of the equation by 2 π
(321/2·π) = r , use calculator, solve and round the answer
51.1 ≈ r
Answer:
24
Step-by-step explanation:
Answer:
(5, 7)
Step-by-step explanation:
M = (x1 + x2/2 , y1 + y2/2)
M = ( 4 + 6 /2 , 7 + 7 / 2)
M = 5, 7
