Answer:
V = 1538.6 cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2h where r is the radius and h is the height
V = pi (7)^2 10
V = 3.14 (49)10
V = 1538.6 cm^3
(The one you have checked so far is not correct, the product of a rational and irrational number is irrational)
The sum of a and b is never rational
b^2 is sometimes rational
^ Those two I know are correct
I forget if A^2 is always rational is correct or not
I hope this helps at all
Answer:
26, 30
Step-by-step explanation:
