Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h
where:
h is the height of the cylinder, r is the radius of the top
Solution:
Given: h = 8.2 ; r = 4 ; pi = 3.14
SAC = 2 (3.14) (42) + 2 (3.14) (4) (8.2)
= 6.28 (16) + 6.28 (32.8)
= 100.48 + 205.984
SAC = 306.464 or 306.46
The surface are of a cylinder whose radius is 10cm and height is 20cm is 1884.96cm2
A cylinder whose radius is 5 and height is 7 has a surface area of 377 units2
This cylinder's height is 6 (5.98) units.
A cylinder whose radius is 2cm and height is 8cm has a total surface area of approximately 125.66cm2 {ADDED} To explain that further, the formula is pi*r^2 X h where r is the radius and h the height.
The surface area of a cylinder is 2*pi*radius*height. In this case it would be 2*pi*5*10 = 314.16
The surface are of a cylinder whose radius is 10cm and height is 20cm is 1884.96cm2
A cylinder whose radius is 6 and height is 14 has a surface area of 754 units2
