S.A=s^2×6
S.A=7.2^2×6
S.A=311.04 ft^2 is your final answer. Hope it help!
To find the volume of a cylinder , you will use the formula
V = Bh, where B is the area of the circular base.
Pi x r^2 x h
pi x 6^2 x 12
V = 432
The volume of the cylinder is 432pi cm³.
This is what we know:4x^2 + 12x + c = (2x + k)^2
<span>
4x^2 + 12x + c = 4x^2 + 2kx + 2kx + k^2
c=9
