What is the value of a <br><br> 6 15<br> -- = ------- <br><br> 22 a

Naily [24]

Step-by-step explanation:

$\frac{6}{22} = \frac{15}{a}$

$\frac{3}{11} = \frac{15}{a}$

$3a = 15 \times 11$

$3a = 165$

$a = \frac{165}{3}$

$a = 55$

5x^2+11x=0 quadratic equation

hammer [34]

$5x^{2} + 11x = 0
$
$5x^{2} + 11x + 0 = 0$
$x = \frac{-(11) +/- \sqrt{(11)^{2} - 4(5)(0)}}{2(5)}$

$x = \frac{-11 +/- \sqrt{121 - 0}}{10}$

$x = \frac{-11 +/- \sqrt{121}}{10}$

$x = \frac{-11 +/- 11}{10}$

$x = \frac{11 + 11}{10}$    $x = \frac{11 - 11}{10}$

$x = \frac{22}{10}$          $x = \frac{0}{10}$

$x = 2.2$       $x = 0$

Find the lateral area of this cone.

tatyana61 [14]

Given:

Radius of the base of the cone = 12 in.

The slant height of the cone = 15 in.

To find:

The lateral surface area of the given cone.

Solution:

The lateral surface area of the cone is:

$LA=\pi rl$

Where, r is the radius of the base of the cone and h is the slant height of the cone.

Putting $r=12,h=15$ , we get

$LA=\pi (12)(15)$

$LA=180\pi$

The lateral surface area of the cone is 180π in ² and the missing value for the blank is 180.
