What is the formula for finding the surface area of a cylinder?
The surface area of a cylinder can be found using the following formula - SA = 2(Pi*r2) + (2*Pi*r)*(H) Pi = Approximately 3.14 r = Radius of the base of the cylinder H = Height of the cylinder
What is the formula for the circumference of a cylinder?
2 x pi x r
Formula for finding the area of a cylinder?
2 pi r h
Who invented formula and the value of pi?
aryabhatta discovered it as 3.1416. value of i is 22/7
What is the area of a circle with a diameter of 8?
Commit to memory A = pi r^2 C = 2 pi r or pi d NB 2r = d This is elementary school maths. Hence if d = 2r 8 , then r = 8/2 = 4 Hence A = pi 4^2 A = 16 pi pi is a constant at 3.141592.... A = 16*3.41592.... = 50.26554.... units^2
Who invented the formula of pi?
There is no formula for Pi, it cannot be represented by any formula. It is a fundamental constant.
What is the circumference of a circle with a radius of 8 feet?
use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi
What is circumference of a circle with a radius of 8 feet?
use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi use the formula 2(pi)r=16pi
What is the arcatangent formula for Pi?
There is only one formula for pi, which is the ratio of the circumference to the diameter of a circle.
What formula is pi d?
It is the formula for finding the circumference of a circle which is the same as 2*pi*radius
What formulas use pi?
the circumference formula uses pi and the formula is pi (3.14) times what ever the diameter is and that's one formula i know and I'm in fifth grade
What is the formula for area and circumference of a circle?
The formula for the area of a circle is pi * radius squared. The circumference of a circle's formula is pi * diameter. NOTE: pi equals approx. 3.14
In the formula of pi what dose s stands for?
there is no s in PI
The formula for pi?
3.141592654
What does the formula Pi r2 mean?
It is the formula used in finding the area of a circle which is pi times radius squared
How can kids remember the formula for circle area and the formula for circle circumference?
Any formula involving a circle will have "pi" in it. Area = pi* radius * radius Circumference = pi * diameter = pi * radius * 2 ( the diameter is just 2 times the radius) Quick way: A = pi r squared C = pi D
Formula of circle?
The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.
