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
