Answer:
u = ± 4
Step-by-step explanation:
Given
u² = 16 ( take the square root of both sides )
u = ± = ± 4
u = - 4, u = 4
It will be 0.0625 because you can use a calculator and do 14/224

Given:
radius of cone = r
height of cone = h
radius of cylinder = r
height of cylinder = h
slant height of cone = l
Solution
The lateral area (A) of a cone can be found using the formula:
where r is the radius and l is the slant height
The lateral area (A) of a cylinder can be found using the formula:
The ratio of the lateral area of the cone to the lateral area of the cylinder is:
Canceling out, we have:
Hence the Answer is option B
He ran 14 km, multiply 6 by 2 and 1/3.
