Find the volume of a cylinder with height 12 cm and diameter 7 cm. A. 73.27 ft2 B. 150.80 ft2 C. 144.37 ft2 D. 169.65 ft2
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?
cylinder . that's what it is for the question .
hmm i think maybe the wrong attatchemnt as in question says raidus is 7 and in picture radius is 3
OOPS ! okay the question is : Find the surface area of the figure below. The answer choices i posted are correct though .
its Cone not cylinder and answer is D
apply the formula for cone pi*r*s + pi *r^2
