Given:
The radius of the given sphere = 1 unit
To find the volume of the sphere.
Formula:
The volume of the sphere of radius r is
Now,
Substituting r=1 and π=3.14 (as given), we get
cube unit
or, 
cube unit
Hence,
the volume of the cube is 4.187 cube unit.
Answer:
21 yards
Step-by-step explanation:
3 yards for 1 mum
3*7 yards for 7 mums
21 yards for 7 mums
I don't know if this is what you mean but here have this
In one revolution of the wheel, a point on the edge travels a distance equal to the circumference of the wheel.
The wheel has radius 1 ft, so its circumference is 2π (1 ft) = 2π ft.
Then the point has a linear speed of
(1/4 rev/s) * (2π ft/rev) = 2π/4 ft/s = π/2 ft/s
