D. 169.65 ft2

Answer 1

volume = pi *r^2 * h

here r (radius) = 3.5 and h = 12 cm


ooppsss - you've drawn a cone not a cylinder!!

which is it?

Answer 2

cylinder . that's what it is for the question .

Answer 3

hmm i think maybe the wrong attatchemnt as in question says raidus is 7 and in picture radius is 3

Answer 4

OOPS !
okay the question is :

The answer choices i posted are correct though .

Answer 5

its Cone not cylinder and answer is D

Answer 6
