you find the surface area of a circle by first finding the area of the circles/ two ends.
you do this by multiplying the diameter by pi then multiply by two, that is both ends put together
then you find the area of the flat part by finding out the circumference of the circle ends, then multiply that by the height of the cylinder.
circumference= pi times the diameter
then add all your calculation together, and you have the surface area of your cylinder :)
It depends on the surface area of what!
A circle.
It is the surface area
The diameter of a circle is 56 cm. What is the circumference of the circle? Use 22/7 to approximate for pi.
Lenght X width = surface area
The area of a circle is 3.141... multiplied by the radius squared.
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!
A circle doesn't have a surface area because it is a 2D object. The area of a circle is = pi r2. if you mean the surface area of a sphere it is = 4 pi r2
The surface area of a circle can be found using the formula A = πr^2, where A is the area and r is the radius of the circle. Simply square the radius and multiply it by π to calculate the surface area.
Surface area of a circle = pi*radius2
The surface area of a circle is calculated as Area = pi x radius2. If the radius is in meters, the area will be in square meters.The surface area of a circle is calculated as Area = pi x radius2. If the radius is in meters, the area will be in square meters.The surface area of a circle is calculated as Area = pi x radius2.

Area of a circle = pi*radius2
the area of the circle is Pi X Radius squared
A cone has two surfaces, lateral surface and its circular surface at the base.The surface area of a cone is the sum of the areas of these two surfaces, i.e. (1) area of the lateral surface and (2) area of its base.Let us consider a right circular cone to find its surface area.The lateral surface area of a right circular cone is π r lwhere,r is the radius of the circle at the bottom of the cone, andl is the lateral height of the coneThe surface area of the bottom circle of a cone is the same as for any circle, π r2Thus the total surface area of a right circular cone is: π r l + πr2 OR π r (l + r)
all you do is find the area of the circle... if you mean find the squares area, find the area of the circle, and then the square's area and subtract the squares area to the circles area
There is no perimeter of a circle. Only flat shapes have perimeters. You can however, find the circumference, surface area, and volume.
