The triangle below is equilateral. Find the length of side x to the nearest tenth.
Gemiola [76]

Answer:

\sqrt{\frac{15}{2} } or 2.738

Step-by-step explanation:

Let’s just look at the triangle on the top with the \sqrt{10} on the top and x on the bottom. (Basically the top half to the equilateral triangle)

There is a small square in the bottom right corner, which indicates that this triangle is a right triangle. This means that we can use the Pythagorean Theorem: a^{2} +b^{2} =c^{2}

We know that \sqrt{10} is our hypotenuse, and therefore our c in our equation. Let’s say that x=a in our equation. Therefore we are left to find b. However, b is half the length of the side of the original equilateral triangle. An equilateral triangle means that all three sides are the same length. Therefore our side would also be \sqrt{10} units long. However we know that b is half of that value, so b=\frac{1}{2}(\sqrt{10}) or \frac{\sqrt{10} }{2}

Plugging these values into the equation:

x^2+ (\frac{\sqrt{10} }{2})^{2}=\sqrt{10} ^{2}

x^{2}=\sqrt{10} ^{2}-\frac{\sqrt{10} }{2} ^{2}

x^{2} =10-\frac{10}{4}

x^{2} =\frac{15}{2}

x=\sqrt{\frac{15}{2} }

This approximately equals 2.738

What is the volume of a hemisphere with a radius of 3.6cm, rounded to the nearest tenth of a cubic cm?
drek231 [11]

Answer:

97.7161 {cm}^{3}

Step-by-step explanation:

<h3>Input Data :</h3>

Length = 3.6 cm

<h3>Objective :</h3>

Find the volume of Hemisphere.

<h3>Formula :</h3>

Volume =

\frac{ 2\pi {r}^{3} }{3}

<h3>Solutions</h3>

volume =

<h3>\frac{2 \times 3.1416 \times 3.6 ^{3} }{3}</h3>

\frac{2 \times 3.1416 \times 46.656}{3}

\frac{293.1483}{3}

volume = 97.7161 {cm}^{3}
