Do congruent spheres have equal surface areas?
Two spheres that are congruent are the same size and shape. Therefore, they would have the same surface area. So this statement is always true.
What- is-the-relationship-between-cylinders'-cones'-and-spheres'-surface area?
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.
What is the surface area of a triangle?
the formula for the area of a triangle is: base times height divided by two.
How do you calculate the Surface area of a prism?
The surface area of a prism is the sum of the areas of each of its sides, plus the two bases. As the number of sides, and their shapes are indeterminate, there is no specific formula. The general formula is (2 x base area) + (perimeter x length)
How do you determine the area of a cylindrical box?
To determine the area of a cylindrical box, you need to calculate the sum of the areas of its curved surface and its two circular bases. The formula for the curved surface area is given by 2πrh, where r is the radius of the base and h is the height of the box. The formula for the area of the circular base is πr^2. Add the two areas together to get the total surface area of the cylindrical box.
Formula for working out area?
There are different formulas for different figures ... also, areas are of two types . They are surface area and lateral s.a.
Surface area formula for the curved part of a cylinder?
Curved surface area of a cylinder excluding the two end pieces = 2*pi*radius*height in square units.
How do you calculate the surface area of any shape?
The method usually fits into one of two general categories: 1). Use the formula that has been developed for the surface area of that particular shape. 2). Break the shape down into pieces with shapes for which the formula for the surface area has been previously developed, and then apply the method of Category #1.
Let A and B be two solid spheres such that the surface area of B is 300 percent higher than the surface area of A The volume of A is found to be k percent lower than the volume of B The value of k is?
This is a very hard question but after various trials I have came up with an answer it is 40%
The formula for caculating the area of a surface?
bh, or base x height. For example: The base of a square is 7in. The height is 9in. The Surface Area would be 63in. For the surface area of a triangle, the formula is bh/2. base times height divided by two. ok, a square would have all four sides the same, just saying.
What is the surface area of a two inch cube?
Surface area formula for a cube is 6 x base x height. So the SA of a 2 inch cube is6x2x2 which equals 24 square inches.
What is the surface area of a sphere with a circumference of 9cm?
You can divide this problem into two steps: 1) Divide the circumference by (2 x pi) to get the radius. 2) Use this radius in the standard formula for the surface area of the sphere.
