surface area of cylinder = area of 2 bases + area of rounded surface = 2*(pi * 7^2) + 2pi*7(2) = 98pi + 28pi = 126pi
It is possible for some cones A and cylinders B. But in general, the assertion is false.
1. Find the surface area of the whole cylinder 2. Find the area of one of the two circles on either end of the cylinder 3. Multiply the circle's area by two and subtract their area from the total surface area 4. Now you have the surface area of an unclosed cylinder!
The surface area of a cylinder prism has round shape and the surface of a rectangular prism has a square shape.
The surface area of a cylinder with a radius of 3.8cm and a height of 11cm is 353.37cm2
true
The relationship between the surface areas of cylinders, cones, and spheres is that the surface area of a cylinder is equal to the sum of the areas of its two circular bases and its curved surface area, the surface area of a cone is equal to the sum of the area of its circular base and its curved surface area, and the surface area of a sphere is equal to four times the area of its circular base.
Calculate them and compare.
The surface area of cylinder with radius equal to 4 and height equal to 9 is 326.725 square units.
A cylinder with a radius of 1 meter and a height of 10 meters has a surface area equal to 69.12m2
surface area of cylinder = area of 2 bases + area of rounded surface = 2*(pi * 7^2) + 2pi*7(2) = 98pi + 28pi = 126pi
Curved surface area includes the area of the length of the cylinder only whereas surface area includes the two bases as well...
It is possible for some cones A and cylinders B. But in general, the assertion is false.
The sphere has a surface area-to-volume ratio of 0.15m^-1, which means it has a relatively low surface area compared to its volume. This indicates a more compact shape. On the other hand, the right circular cylinder with a ratio of 2.2m^-1 has a higher surface area compared to its volume, suggesting it is more elongated or spread out.
it would be faster for the right cylinder
face or surface are related words for a surface area of a cylinder
The rate of diffusion would be faster for the right cylinder.
