Answer: 5500cm.
Step-by-step explanation:
A revolution corresponds to circumference of the bicycle wheel.
The radius of the circle = 70/2 since two radii makes a diameter.
Therefore r = 35cm
Circumference of a circle = 2πr or πd where π = 3.142 or 22/7
We now have = 2 x 22/7 x 35
Therefore 0ne revolution = 220cm.
Therefore, the distance traveled by making 25 revolution
= 220 x 25
= 22000/4
= 5500cm.

Answer:
x = 6; 6 weeks
Step-by-step explanation:
Hi!!
Okay, so here is the equation needed to solve:
85.00 = 25.00 + 12.00x
Subtract 25 from both sides
85 -25 = 25 - 25 + 12x
Then, you get:
55 = 12x
Divide 55 by 12
55/12 =x
so x = 6
Hope this helps!
