To find the surface area of a cylinder, you need to add the areas of its two circular bases and the area of its curved surface.
First, find the area of one circular base by using the formula for the area of a circle: A = πr^2, where A is the area and r is the radius of the circular base.
Next, multiply the area of the circular base by 2, since there are two circular bases in a cylinder.
Then, find the area of the curved surface by multiplying the circumference of the circular base by the height of the cylinder. The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.
Finally, add the areas of the two circular bases and the curved surface to get the total surface area of the cylinder.
To find the surface area of a cone, you need to find the area of its circular base and the area of its curved surface.
First, find the area of the circular base using the formula A = πr^2, where A is the area and r is the radius of the circular base.
Next, find the area of the curved surface by multiplying the slant height (l) of the cone by the circumference of the circular base. The slant height is given by the formula l = √(r^2 + h^2), where h is the height of the cone.
Finally, add the area of the circular base and the curved surface to get the total surface area of the cone.
