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

Answer:
c
Step-by-step explanation:
168 degrees is the supplement of 12.
Answer:
1.8 mL
Step-by-step explanation:
The amount you need will be the dose divided by the concentration.
(0.7 g)/(0.400 g/mL) = 7/4 mL = 1.75 mL ≈ 1.8 mL
The dosage will be about 1.8 mL.
