you would multiply 10 x -12 by distributing the 10 into the parenthesis.

The answer would be negative because a postive times a negative is a negative.

The answer is -120

Find the volume of a pyramid with a square base, where the perimeter of the

lianna [129]

Answer:

$42.7\,\,cubic\,\, meters$

Step-by-step explanation:

Given: Perimeter of base of a pyramid = 12.8 m

Height of the pyramid = 12.5 m

To find: volume of a pyramid

Solution:

Perimeter of base of a pyramid = 12.8 m

As base of the pyramid is a square,

12.8 = $4(side\,\,of\,\,a\,\,square)$

side of a square = $\frac{12.8}{4}=3.2\,\,m$

Area of a square (A) = $(side\,\,of\,\,a\,\,square)^2=(3.2)^2=10.24\,\,m^2$

Height of the pyramid (h) = 12.5 m

Volume of the pyramid = $\frac{Ah}{3}=\frac{1}{3}(10.24)(12.5)=42.7\,\,cubic \,\,meters$

$Sin\theta=\frac{-2}{7}$

we have

$cosec \theta=\frac{1}{Sin\theta} =\frac{1}{\frac{-2}{7}}\\=-\frac{7}{2}$
