Find x.______________a0

velikii [3]

Answer:

$x=4$

Step-by-step explanation:

Before we find x, we need to set up this triangle a little more. We need to find the triangle's altitude before we can solve for x. We will use the heartbeat method to find the altitude.

Let altitude = y; solve for y:

$\frac{2}{y}=\frac{y}{6}$

$y^2=12$

$y=\sqrt{12}$

$y=2\sqrt{3}$

Now that we know the altitude, we can use the Pythagorean Theorem to find the hypotenuse (x).

$a^2+b^2=c^2$

$2^2+(2\sqrt{3})^2=c^2$

$4+12=c^2$

$c^2=16$

$c=4$

Since c and x are the same; c is just the hypotenuse in the Pythagorean Theorem.

$x=4$

Grace [21]

Answer: $77.283km^{2}$

Step-by-step explanation:

The formula for the lateral area of a cone $L.A$ is:

$L.A=\pi r h$

Where:

$r=10km$ is the radius of the circular base of the cone

As we know its diameter $d=20km$ , its radius is $r=\frac{d}{2}=10km$

$h=2.46km$ is the height of the cone

$L.A=\pi (10km)(2.46km)$

$L.A=77.283km^{2}$ This is the lateral area of the volcano with the shape of a cone
