Can someone help me with these questions
Varvara68 [4.7K]

Answer:

1.) can not be found

2.)V=11403.98

3.)

Step-by-step explanation:

volume = π r×r × H

r = Radius

H = height

π = 3.14

the first one does not have a radius so therefore we can NOT find the volume

the second one is π×(11×11) ×30 =11403.98

the 3rd one is π× (10×10) ×5 =1570.79

hope this helped
