The lateral surface area of cone A is exactly 1/2 the lateral surface area of cylinder B. Cone A radius is r and height h - Cyli
Mrac [35]

The ratio of the <em>lateral surface</em> area of cone A to the <em>lateral surface</em> area of cylinder B is equal to r = \frac{1}{2}\cdot \frac{\sqrt{r^{2}+h^{2}}}{h}. (Correct choice: False)

<h3>What is the ratio of lateral area of cone to the lateral area of the cylinder?</h3>

In accordance with <em>space</em> geometry, the <em>lateral</em> areas of the cone and cylinder are described by the following equations:

Cone

A_{l} = \pi \cdot r \cdot \sqrt{r^{2}+h^{2}}     (1)

Cylinder

A_{l} = 2\pi\cdot r\cdot h     (2)

If we divide (2) by (1), then we have the following ratio:

r = \frac{1}{2}\cdot \frac{\sqrt{r^{2}+h^{2}}}{h}

The ratio of the <em>lateral surface</em> area of cone A to the <em>lateral surface</em> area of cylinder B is equal to r = \frac{1}{2}\cdot \frac{\sqrt{r^{2}+h^{2}}}{h}. (Correct choice: False)
