Mrs. Sue Mrs. Sue!!!!!!!!! Pls help!!!! I am not good at this. Pls help me figure this out. And, PLs dont give a link. Thank You. P.s I dont even have an estimate.
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.
surface area:
A=2*π*r*h + 2*π*r^2
volume:
V=π*r^2*h
Those are the formulas; just plug in the numbers.
Post your answers here and I'll check them.
Of course, I'll be happy to help you with this problem! To find the surface area and volume of a cylinder, we'll need to use the formulas for each.
1. Surface Area:
The surface area of a cylinder is given by the formula: SA = 2πrh + 2πr^2, where "r" represents the radius, and "h" represents the height of the cylinder.
To calculate the surface area, plug in the given values:
r = 3.5 ft
h = 14 ft
SA = 2π(3.5)(14) + 2π(3.5)^2
To approximate the answer to the nearest tenth of a foot, we can use a calculator or the value of π as 3.14.
SA ≈ 2(3.14)(3.5)(14) + 2(3.14)(3.5)^2
2. Volume:
The volume of a cylinder is given by the formula: V = πr^2h.
To calculate the volume, use the same values for "r" and "h":
V = π(3.5)^2(14)
Again, you can approximate π as 3.14 for this calculation.
V ≈ (3.14)(3.5)^2(14)
By plugging in the values, you can then use a calculator to evaluate the expressions and find the surface area and volume of the cylinder to the nearest tenth of a foot.
