The unicycle moves a distance of 251.20cm if the wheel turn once and the wheel must rotate 32 times to cover a distance of 100m
<h3>Circumference of a circle</h3>
The formula for calculating the circumference of a circle is given as:
C = 2pi r
r is the radius of the circle
a) r = 80/2 = 40cm
C = 2(3.14)(40)
C = 251.20 cm
Hence the unicycle moves a distance of 251.20cm if the wheel turn once
b) Number of revolution * 2pi r = distance covered
n * 2(3.14)(50) = 10000
314n = 10000
n = 10000/314
n =32
Hence the wheel must rotate 32 times to cover a distance of 100m

14/175 x 100 = 8%
answer is A. 8 (first choice)
Answer:
35 minutes
Step-by-step explanation:
Take the lastest time and subtract the earliest time
9:45
9:10
------------
:35
35 minutes
m is the slope
b is the y-intercept
so that means that the y-intercept of
is
C=10pi
C=2(r)pi so r=5
A=pi(r)^2
so A=pi(5)^2
A=25pi
