Find the lateral area for the pyramid with the equilateral base

likoan [24]

<h3>The lateral area for the pyramid with the equilateral base is 144 square units</h3>

Solution:

The given pyramid has 3 lateral triangular side

The figure is attached below

Base of triangle = 12 unit

Find the perpendicular

By Pythagoras theorem

$hypotenuse^2 = opposite^2 + adjacent^2$

Therefore,

$opposite^2 = 10^2 - 6^2\\\\opposite^2 = 100 - 36\\\\opposite^2 = 64\\\\opposite = 8$

Find the lateral surface area of 1 triangle

$\text{ Area of 1 lateral triangle } = \frac{1}{2} \times opposite \times base$

$\text{ Area of 1 lateral triangle } = \frac{1}{2} \times 8 \times 12\\\\\text{ Area of 1 lateral triangle } = 48$

Thus, lateral surface area of 3 triangle is:

3 x 48 = 144

Thus lateral area for the pyramid with the equilateral base is 144 square units

What are the solutions of the following system? y=-2x^2 y=x-2

vovikov84 [41]

Answer:

x = 0.781 , y = -1.219

and

x = -1.281 , y = -3.281.

Step-by-step explanation:

Since both of the x terms are equal to y we can equate the x terms:-

-2x^2 = x - 2

2x^2 + x - 2 = 0

x = [-1 +/- √(1^2 - 4*2*-2) ] / 4

= ( - 1 +/- √(17)) / 4

= 0.781, -1.281.

When x = 0.781 y = 0.781 - 2 = -1.219.

when x = -1.281 , y = -1.281 - 2= -3.281.

What is the area of a circle with 20cm diameter

lesya [120]

Well that's a 10cm radius and the formula for area of a circle is A= 3.14•R(squared). So to plug that in, that would be 3.14 • 10 squared or 3.14 • 100. 3.14•100=314
