A cone and a cylinder have equal radius, r, and equal altitudes, h. If the slant height of the cone is l, then the ratio of the

77julia77 [94]

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:

$A\text{ = }\pi rl$

where r is the radius and l is the slant height

The lateral area (A) of a cylinder can be found using the formula:

$A\text{ = 2}\pi rh$

The ratio of the lateral area of the cone to the lateral area of the cylinder is:

$\pi rl\text{ : 2}\pi rh$

Canceling out, we have:

$\begin{gathered} =\frac{\pi rl}{2\pi rh} \\ =\text{ }\frac{l}{2h}\text{ or l:2h} \end{gathered}$

Hence the Answer is option B

Hi there!

$\large\boxed{a = 6 m/s^{2}}$

Use the kinematic equation to solve for acceleration:

$a = \frac{v_{f}-v_{i}}{t}$

Where:

vf = final velocity

vi = initial velocity

t = time

Plug in the given values:

$a = \frac{65-35}{5}\\\\a = 30 / 5 \\\\=6 m/s^{2}$
