cylinder with a height of 21 dm and a radius of 3 dm with solution​

Sagot :

The volume of a cylinder is equal to the area of the base πr² times the height.

π × (radius)² × (height)

Substitute the values of the radius r = 3 and height h = 21 into the formula to find the volume of the cylinder. Pi π is approximately equal to 3.14.

π × 3² × 21

Raise 3 to the power of 2.

π × 9 × 21

Move 9 to the left of π.

9 × π × 21

Multiply 21 by 9.

189π
