Pyramid x is similar to pyramid y. The surface area of pyramid x is 135 cm² and the surface area of pyramid y is 240 cm². if the volume of pyramid x is 189 cm³. then what is the volume of pyramid y?
A. 448 cm³
B. 336 cm³
C. 1061.9 cm³
D. 252 cm³

B. 336 cm^3

Step-by-step explanation:

Set up a proportion: 135/x=240/y

135/189=240/y

135y=189(240)

135y=45360

y=336

Therefore, B. 336 cm^3

I hope this helped and have a good rest of your day!

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
