A cylinder has a height of 14 millimeters and a radius of 16 millimeters. What is its volume?
pantera1 [17]

Answer:

11253.76

Step-by-step explanation:

To find the volume of a cylinder we must utilise the volume of cylinder formula which is

→ Volume of cylinder = π × r² × h

Where 'r' is the radius and 'h' is the height so let's start substituting in the values,

→ Volume of cylinder = π × r² × h

⇒ Substitute in 3.14 for π, 14 for 'h' and 16 for 'r'

→ Volume of cylinder = 3.14 × 16² × 14

⇒ Simplify

→ Volume of cylinder = 11253.76

So a cylinder has a height of 14 millimetres and a radius of 16 millimetres has a volume of cylinder 11253.76 inches³

Finding the Volume of a Rectangular Pyramid

Your overall formula for finding the volume of these multi-faceted shapes is V = (l x w x h) / 3. Basically, your first step is finding the area of the base by multiplying length by width. Once you determine the area of the base, multiply that by the height.

in 18 days, 20 workers can build a school. How many days would it take if there were only 12 workers?​
Marat540 [252]

To build a school;

20 workers -> 18 days.

So 1 worker -> 18/20 days.

So; 12 workers -> (12×18)/20 days.

-> (12×9)/10 days

->10.8 days.

so 10.8 days is your answer.

Hope it helps...

Regards;
