Answer:
1 : 1
Step-by-step explanation:
When a circle is inscribed in a cylinder, the height of the cylinder is equal to the diameter of the sphere and the radius of the cylinder is same as that of the sphere.
Let the radius of sphere is r.
height of cylinder, h = 2r
radius of cylinder = r
Surface area of sphere, A = 4πr²
lateral surface area of cylinder, A' = 2 πrh
A' = 2πr x 2r = 4πr²
The ratio of surface area of sphere to the lateral surface area of cylinder is 1 : 1.
For this case, the first thing you should know is the following conversion of units:
360 degrees = 2pi radians
Applying the conversion we have:
θ = 180 * (2pi / 360)
Rewriting we have:
θ = pi
Answer:
the angle to radians is:
θ = pi
Multiply it all together. 130,000 ways to order
ULL GO 130KM PER HOUR
SO THAT MEANS 3 X 130 = 390
