A right pyramid with a regular hexagon base has a height of 3 units If a side of the hexagon is 6 units long, then the apothem i
Setler79 [48]

Answer:

Part a) The slant height is 3\sqrt{2}\ units

Part b) The lateral area is equal to 54\sqrt{2}\ units^{2}

Step-by-step explanation:

we know that

The lateral area of a right pyramid with a regular hexagon base is equal to the area of its six triangular faces

so

LA=6[\frac{1}{2}(b)(l)]

where

b is the length side of the hexagon

l is the slant height of the pyramid

Part a) Find the slant height l

Applying the Pythagoras Theorem

l^{2}=h^{2} +a^{2}

where

h is the height of the pyramid

a is the apothem

we have

h=3\ units

a=3\ units

substitute

l^{2}=3^{2} +3^{2}

l^{2}=18

l=3\sqrt{2}\ units

Part b) Find the lateral area

LA=6[\frac{1}{2}(b)(l)]

we have

b=6\ units

l=3\sqrt{2}\ units

substitute the values

LA=6[\frac{1}{2}(6)(3\sqrt{2})]=54\sqrt{2}\ units^{2}

Find the radius of a circle with an area of 380 in².
Likurg_2 [28]

Answer:

11 inches

Step-by-step explanation:

The area of a circle can be found using:

a=\pi r^{2}

We already know that the area is 380, so we can substitute 380 in for a.

380=\pi r^2

Now, we need to find the radius. To do this, we need to get r by itself

First, divide both sides by pi

380/\pi =\pi r^2/\pi

120.95775675=r^2

Since r is being squared, we need to take the square root of both sides

\sqrt{120.95775675}=\sqrt{r^2}

10.9980796846=r

If we round to nearest whole number, our radius is 11 inches
