Find the volume of a cylinder with a diameter of 11 inches and a height of 13 inches. Round to the nearest tenth.
- 1235.4
- 123.4
- 1235
- 1234.5
Hint:
The formula of the volume of the cylinder is 
.
The correct answer is: 1235.4
Step1:We know that the volume of the cylinder is 
, Where r is the radius of the cylinder and h is the height of the cylinder.
Step2:Here we are given the diameter of the cylinder so first we will find the radius of the cylinder by dividing the diameter by 
,i.e. 
and 
.
Step3: Now we will put the values of r and h in the formula of the volume of the cylinder to find the volume of the cylinder.
So, the volume of the cylinder is 
.
