First of all, that should be "4 pi radius-squared" to find the surface area of a sphere.
It's not too hard to show why, but first, you have to be comfortable enough with calculus
that the idea of a triple integral doesn't scare you. We're pretty sure that the question
can't be answered without spending a few minutes working with one of those.
It depends on what information you have: its radius and slant height, radius and volume, radius and surface area, surface area and volume, etc.
Finding the radius of a Sphere by using the surface area is a multi-step mathematical equation. The radius (r) of a sphere with a surface area of 1742400ft is 372.365ft.
Volume = 4/3 * pi * radius * radius * radius Surface Area = 4 * pi * radius * radius
Base Area = pi x radius x radius Curved Surface Area = 2 x pi x radius x height Total Surface Area = 2 x pi x radius x (radius + height)
Total surface area in square units = (pi*radius*slant length)+(pi*radius squared)
2πrh, where 'r' is the radius and 'h' is the height.
The answer depends on what information you are given: volume and radius or diameter, or surface area and radius, etc.
Before finding it's surface area, you'd have to get it's basic measurements. You need it's height and it's radius. The surface area can then be worked out as 2πr(r + h), where r is it's radius and h is it's height.
Finding the area of a circle: pi*radius2 Finding the circumference of a circle: 2*pi*radius or diameter*pi Finding the surface area of a sphere: 4*pi*radius2
The answer depends on what information you are given: volume and height, or surface area and height, etc.
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
2 X Pi X radius X height = area Circumference X height = area (times two if you want inside and outside assuming the walls are of zero thickness)
