2×6 ones= 12 ones
2× 4 tens(40)=80(8 tens)
tens(10)+1 ten=20(2 tens)
2×3 hundreds(300)=600(6 hundreds)

The volume of the cylinder is 900 cubic inches
<em />
Step-by-step explanation:
Given
Let V1 represent the volume of a cone and V2 represents the volume of a cylinder

Required
Determine the volume of a cylinder with same dimension
The volume of a cone is calculated as:

The volume of a cylinder is calculated as:

Since, the cone and cylinder have the same dimensions, we can substitute
for
in 
So, we have:

Multiply both sides by 3



Substitute
for 


<em>Hence, the volume of the cylinder is 900 cubic inches</em>
Answer:
the answer is 21 i know right
