What is the formula for the total surface area of a cylinder?
2nr^2 + 2nrh
I hope y'all know not to put an actual n. The n is meant as Pi
the answer is =
2nr^2 + 2nrh
2πr^2 + 2πrh
okay that's the symbol I meant to put but anyways that's the answer.
The formula for the total surface area of a cylinder is given by:
2πr(r + h)
where r is the radius of the base of the cylinder and h is the height of the cylinder.
Find the surface area of a cylinder with a radius of 4 cm and a height of 2 cm. Use the approximation of 3.14 for pi.
The formula for the total surface area of a cylinder can be obtained by adding the areas of the two circular bases and the lateral surface area. To find the area of each circular base, use the formula for the area of a circle, which is π * r^2, where π is a mathematical constant approximately equal to 3.14159, and r is the radius of the circular base.
To find the lateral surface area, multiply the circumference of the circular base by the height of the cylinder. The circumference of a circle can be found using the formula 2 * π * r, where r is the radius of the circular base.
By adding the areas of the two bases and the lateral surface area, we get the formula for the total surface area of a cylinder:
Total Surface Area = 2 * (π * r^2) + (2 * π * r * h)
Where r is the radius of the circular base and h is the height of the cylinder.
thats not working
AI BOT
that isnt working
actually nvm I'll just put the answers
