The radius of a cylinder is 3.5 ft. The height is 14 ft. Find the surface area and volume of the cylinder to the nearest tenth of a foot.
I think the volume is 538.51 in^3.
I just don't know the SA. Is it, possibly, 164.85 in^2. Or, no where closer than that answer?
IM RIGHT
Given:
radius : 3.5 ft
height : 14 ft
Surface Area of a cylinder = 2πrh + 2πr²
S.A. = 2 * 3.14 * 3.5ft * 14ft + 2 * 3.14 * (3.5ft)²
S.A. = 307.72ft² + 2 * 3.14 12.25ft²
S.A. = 307.72ft² + 76.93ft²
S.A. = 384.65 ft²
Volume of a cylinder = πr²h
V = 3.14 * (3.5ft)² * 14ft
V = 3.14 * 12.25ft² * 14ft
V = 538.51 ft³
I just need a SIMPLE version of the formula to I can do the math with out getting a headache. That literally all I want.
Given:
radius : 3.5 ft
height : 14 ft
Surface Area of a cylinder = 2πrh + 2πr²
S.A. = 2 * 3.14 * 3.5ft * 14ft + 2 * 3.14 * (3.5ft)²
S.A. = 307.72ft² + 2 * 3.14 12.25ft²
S.A. = 307.72ft² + 76.93ft²
S.A. = 384.65 ft²
Volume of a cylinder = πr²h
V = 3.14 * (3.5ft)² * 14ft
V = 3.14 * 12.25ft² * 14ft
V = 538.51 ft³
I hope this helps it took me a bit to get this but try to change it up a bit
ok this is kinda hard but i have the answers
the surface area of
the cylinder is
384.85 and the
volume is 528.51
