The surface area formula for cylinders and prisms is
SA = 2B + l
where B is the area of your base
l is your lateral area which is equal to l=ph where p is the perimeter (or circumference in your case) of the base and h is the altitude
All cylinders have circular bases so the base area b = pi * r^2 where r is the radius of the circle
the formula for circumference is 2*pi*r, where r is again the radius
So, l = 2*pi*r*h
And finally
SA = 2*pi*r^2 + 2*pi*r*h
This can be simplified to
SA = 2*pi*r*(r+h)

Find the surface area of the right triangular prism?
the defnition of find the surface area of triangular prism and cylinder
What is the formula used to find the surface area of a cylender?
surface area of right circular cylinder = 2 pi r h +2 pi r2
Which of the following formulas would find the surface area of a right cylinder where h is the height r is the radius la is the lateral area and ba is the base area?
BA+LA2(Pi)r2 + 2(Pi)rh
A rectangular piece of sheet iron 625cm squared in area to form a cylinder 9 cm in diameter. Find the height and the volume of this cylinder.?
First, find the surface area of the cylinder using the formula SA = pi * diameter * height The surface area of the cylinder will equal the area of the rectangular sheet. So you can then solve for the height of the cylinder, Height = 625cm2 / (pi * 9cm) = 22.1 cm Using the height and diameter of the cylinder we can find the volume with the following formula, Vol = (pi / 4) * (diameter)2 * height Vol = (pi/4)*(9cm)2 * 22.1cm = 1405.9 cm3
