Answer 1

Answer: 1329.8 cubic cm.

Step-by-step explanation: First find the radius of the base by dividing the diameter (11) by 2. 11/2=5.5.

Then square the radius (5.5). 5.5^2=30.25.

Then multiply this by pi (3.14). 30.25*3.14=94.985.

Next multiply that by the height (14). 94.985*14=1329.79

Finally round this to one decimal place by rounding up the 7 to get 1329.8.

Answer 2

volume of a cylinder =5319.16 cm³

Explanation:

given the radius of the cylinder = 11cm

height of the cylinder = 14cm

recall that the formulae for finding the volume of a cylinder = πr²h

volume of a cylinder = πr²h

volume of a cylinder = 3.14 x (11cm)² x 14cm

volume of a cylinder = 3.14 x 121cm² x 14cm

volume of a cylinder =5319.16 cm³

the volume of the cylinder is evaluated to be 5319.16cm³ and the formulae used is πr²h
