Question

A company makes similar cylindrical containers in two sizes, as shown in the table below.

Containers

Radius (in centimeters)

Volume (in cubic centimeters)
Type 1

4

?
Type 2

7

1231.66

What is the volume, in cubic centimeters, of Type 1 containers?

2111.42

2155.41

402.17

229.81

Answer 1

Do you know how to calculate the volume of a cylinder?

Answer 2

v=3.14r2h

Answer 3

\[\left( pi 4^{2}h \over pi 7^{2}h \right)=\left( x \over 1231.66 \right)\] where x is the volume of the smaller cylinder. Solve for x.

Answer 4

229.81

Answer 5

That is not the answer I got. Let me check my calculations again.

Answer 6

thats what i got and i can prove it to you hold on
