Answer:
Therefore the value of given expression when r = 14 and s = 8 is

Step-by-step explanation:
Given:

To Find:
Value of above equation when r = 14 and s = 8
Solution:
.............Given
Put,


Now 7 × 2 = 14 and 8 will cancel each other we get

Therefore the value of given expression is

Step-by-step explanation:
12 to the 2nd power=144
15 to the 2nd power =225
225-144=81
square root of 81 is 9
Answer:
F. None of the above
Step-by-step explanation:
A cone is produced by rotating the shape about line m.
The height of the cone will be 0.5 because it's perpendicular to the base.
Since the height is 0.5, the answer is not A or B.
The circular base is formed by the line split into two "1"s. Each "1" is the radius, together, the diameter of the base.
Since r = 1, the answer is not C.
Since d = 2r = 2(1) = 2, the answer is not D.
∴ The answer is none of the above, F.
