Answer:

1. 942

2. 753.6

Step-by-step explanation:

1

a is the diameter, a=10. Therefore the radius (r) is 5.

b is the height, therefore the height (h) is 12

The volume of a cylinder is founding using the formula V=πr²h:

V=πr²h

V=(3.14)(5²)(12)=942

2

Here, r=4cm, and h=15cm:

V=πr²h

V=(3.14)(4²)(15)=753.6
