The surface areas of two similar figures are 4 in2 and 9 in2. If the volume of the larger figure is 216 in3, what is the volume
OverLord2011 [107]
We know that
surface area smaller figure=scale factor²*surface area larger figure
scale factor=√[surface area smaller figure/surface area larger figure]
scale factor=√[4/9]-----> scale factor=2/3
so
volume smaller figure=scale factor³*volume larger figure
volume smaller figure=(2/3)³*216----> (8/27)*216----> 64 in³

the answer is
the volume of the smaller figure is 64 in³

What is the answer to 3(2x)=4x+4
Sholpan [36]

3(2x)=4x+4

do the bracket first

(3)(2x)= 6x

6x= 4x+4

move 4x to the other side

sign changes from +4x to -4x

6x-4x=4x-4x+4

6x-4x= 4

2x= 4

divide by 2

2x/2=4/2

x=2

Answer: x= 2

What is 325.623 rounded to the nearest tenth
Fittoniya [83]
325.6 is your answer :

If the number that comes before it is smaller than 5, you keep the number the same. If it’s larger than 5, then you boost it up one. For example, if it was 325.683, you’d round that to 325.7.

Hope that helps!
