Two pyramids are similar with a ratio of surface areas of 25:36. Find the volume of the larger pyramid given that the first has

ki77a [65]

Answer:

432m^3

Step-by-step explanation:

The computation of the volume of the larger pyramid is shown below:

Let us assume the volume of the larger pyramid be x

Given that

The ratio of two pyramids is 25:36

We can say that

The Ratio of side = (The ratio of surface area)^ $\frac{1}{2}$ = $\frac{5}{6}$

Now

ratio of volume = (ratio of side)^3 = $\frac{5^{3}}{6^{3}}$ = 125 : 216

Based on the above information, the calculation is as follows

$\frac{125}{216} = \frac{250}{x}$

So,

$x = \frac{250 \times 216}{125}$

= 432m^3

What is the quadratic formula of 4x2+3x+5=0

maxonik [38]

4x² + 3x + 5 = 0
x = -3 +/- √(3² - 4(4)(5))
 2(4)
x = -3 +/- √(9 - 80)
 8
x = -3 +/- √(-71)
 8
x = -3 +/- √(71 × (-1))
 8
x = -3 +/- √(71) × √(-1)
 8
x = -3 +/- 8.43i
 8
x = -0.375 +/- 1.05375i
x = -0.375 + 1.05375i x = -0.375 - 1.05375i
