If you know the perimeter how do you find the area?
Perimeter equals to 2 times the length plus 2 times the breadth. Area equals to length multiply by breadth
What is the surface area of a right cone?
Entire surface area of a cone: pi*radius^2 plus pi*radius*slant length
What is the equation for the Surface Area of a cylinder?
If the cylinder has radius R and length L , the curved part of the surface has area 2piRL and each of the ends has area piR^2. The total surface area is the sum of the curved part plus two ends.
Formula for surface area of a pyramid?
The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.
What is the formula for finding the surface area of the wall of a cylinder?
Divided into 3 sections (the rounded middle-section and the two circular ends), the surface afrea is equal to the area of the circular end multiplied by two (which equals pi X the radius of the circle squared) plus the circumference of the circular end multiplied by the length of the cylinder. Therefore total surface area = 2(pi X radius squared) + length(pi X 2 X radius)
