R + R = 10
4/3 r³ π : 4/3 R³ π = 27 : 343
r ³ : R ³ = 27 : 343 / ∛
r : R = 3 : 7
3 R = 7 r
R = 7 r / 3
r + 7 r / 3 = 10 / · 3
3 r + 7 r = 30
10 r = 30
r = 30 : 10
r = 3
Answer: the radius of the smaller sphere is 3.
The Range of a function is the set of all values that that function can take.
Given the sine function f(x)=sinx,
This function is the function which calculates the sine of the values of x.
According to the definition of the sine of an angle x in the unit circle,

,
so the sine of an angle is always larger or equal to -1, and smaller or equal to 1.
This means that the values that the sine function takes are any values between -1 and 1, inclusive.
This determines the Range of the sine function.
So the Range of the sine function is [-1, 1]
