Question

Help please


17. A cone has a radius of 40 cm and a volume of 1,875 cm3
. What is the volume of a similar cone with a
radius of 16 cm?
(1 point)
120 cm3
300 cm3
75 cm3
750 cm3

I have no Idea

Answer 1

Write the equation for the volume of a right circular cone:

V = ?

Answer 2

how is this happening

Answer 3

?????

Answer 4

So you need to set those two equal to each other since they're similar shapes

Answer 5

For instance: a 2x2 square is similar to a 4x4 square
you would then set that up as 4=16area
But for this question, there is an "x" value, a missing piece

Answer 6

How do you think you'll set up this equation?

Answer 7

Hint: It'll be in a form of a fraction

Answer 8

radius 40 ---- volume 1875
radius 16 ---- volume x
------------------------

x = 16*1875/40 = ?
