Acylinder has a height of 1.2 cm and the following base. if all the dimensions of the cylinder are tripled, what will be its new volume? 2,826 mm3 8,478 mm3 25,434 mm3 2,543.4 mm3

Volume of new cylinder =   25446.9 mm³.

Step-by-step explanation:

Given  : A cylinder has a height of 1.2 cm and radius = 5 mm.

To find : If all the dimensions of the cylinder are tripled, what will be its new volume.

Solution : We have given that

Height of cylinder = 1.2 * 10 = 12 mm.

radius = 5 mm.

Volume of cylinder = pi * radius² * height.

Volume of cylinder = 3.14 * (5)² * 12

Volume of cylinder = 942.48 mm³.

If the dimensions are tripled

Height = 12 *3 = 36 mm

Radius = 5 * 3 = 15 mm

Volume =  pi * radius² * height.

Volume = 3.14 * (15)² * 36

Volume of new cylinder =   25446.9 mm³.

Therefore,  Volume of new cylinder =   25446.9 mm³.

the answer is b i just did that
