The answer is a.8
3x11-5x5= 33-25=8
Answer:
1436.75504 or 1372/3π cm^3
Step-by-step explanation:
The volume of a sphere can be found using:
V = 4/3 πr^3
We know the radius is 7, so we can substitute 7 in for r
V = 4/3 π7^3
Evaluate the exponent
V = 4/3 π 343
If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343.
v= (4/3*343)π
v=1372/3π
If we want an exact answer, multiply 1372/3 and pi
v=1436.75504
So, the volume is 1436.75504 or 1372/3 π cm^3

Answer:
Answer is
sine = 0.769
cosine = 0.6389
Step-by-step explanation:
Given a right angle triangle
Where Height of triangle = 10
And Hypotenuse of triangle = 13
Then, we know Sin Ф = Height/ hypotenuse
or SinФ = 10/13
or Ф = arcsin (10/13)
or Ф = 50.285°
So , sin Ф = sin 50.285° = 0.769
Next we need to cosine.
i.e cos Ф = cos 50.285° = 0.6389
Hence we got, sine = 0.769
And cosine = 0.6389
