The formula is:
Circumference x Height (unwrap the cylinder, and you'll see why). Assuming you meant lateral surface area:
48 ft2.
But adding the 2 bases, we have:
2pi*r = 8
r*pi = 4
r = 4/pi
Thus, squaring, and multipling by pi (and 2):
16/pi2 * pi * 2 = 32/pi
32/pi + 48 = (48pi + 32)/pi, which is approximately 58.1859163579 ft2, rounded up.
you divide the surface area by the circumference.
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
Take the circumference and multiply it by it's height to get the lateral surface area.
2,5*2,5*3,14*4=78,5
Find the circumference of the circles (the ends) and multiply it by the height of the cylinder. Then add that to the area of the ends.
you divide the surface area by the circumference.
Find the radius by dividing the circumference by 2pi then find the area of the base and multiply it by the height
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
Take the circumference and multiply it by it's height to get the lateral surface area.
2,5*2,5*3,14*4=78,5
Find the circumference of the circles (the ends) and multiply it by the height of the cylinder. Then add that to the area of the ends.
The circumference is 24*Pi yards.The surface area = circumference x heightthereforeheight = surface area / circumference = 1206 sq.yd. / 24*Pi yd. = 15.9951 yards or 16 yards (rounded).
Divide the surface area by the circumference of the circle, which is a product of the diameter x Pi. Essentially, an unrolled cylinder is a rectangle.
Divide the circumference by the value Pi - this will give you the diameter.
S = C2/pi where S is the surface area, C is the circumference.
height * circumference (picture the cylinder cut along the long edge, then rolled out flat, and you would measure height * width) note: if you need to include the circles at the top and bottom of the cylinder, add (circumference / 3.1415926 )^2 * 2 * 3.1415926
To find the lateral area of a cylinder, multiply the circumference (πd) by the height (πdh). After you have this, you can find the total surface area by adding twice the area of the base (2πr2).(Lateral area = πdh), (Surface area = πdh + 2πr2).
