How do you find the perimeter and area of a circle?
perimeter (circumference): diameter times pi (3.14) area: radius times radius times pi (3.14) Area = pi*radius squared Circumference = 2*pi*radius or pi*diameter
What is the circumference of a circle whose area is 100 pi?
The formula for finding the area of a circle is pi times the radius squared. Let's find the radius of the circle. 100 pi/ pi= 100. Squarerooted, the radius is 10. The formula for finding the circumference of a circle is 2 times pi times the radius. So, plug in: 2 times pi times 10 equals 20 pi! Your final answer: 20 pi (or, if you use decimals, approximately 62.8)
Surface area of cone?
(pi times radius squared) plus (pi times radius times slant).
What does pi radius 2 mean?
That would depend if you mean 2 times the radius times pi (2*pi*r) or the more likely scenario pi times radius squared (pi*r2). 2*pi*r is the formula of the circumference of a 2d circle. Pi*r2 is the formula of the area of a 2d circle.
What is the circumference of a circle that has a radius of 38 inches in terms of pi?
The circumference C = 2 r times pi C = 76 inches times pi. pi = 3.141592654...
What is pi times pi divided by pi plus pi minus pi times pi?
the same as pi squared, which is 9.86960440109
How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
What are the two formulas for circumference?
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
What is pi times pi equal?
pi^2
What is the formula for the area of acircumferenceof a circle is?
area: (pi) times radius2 circumference: (pi) times diameter OR 2 times (pi) times radius :)
What is 4 times pi times pi times 4 divided by 2?
4 times pi times 4 divided by 2 is 78.9568352087
What times pi 46?
Pi 46 is solved by taking pi and multiplying by 46. So pi times 46 = 144.513262.
What is the square root of pi times pi?
The square root of pi times pi is simply pi. Because pi*pi=pi squared, the squared and the square root will cancel each other, leaving just pi.
What is formular of circle?
Area of a circle: pi times radius squared Circumference of a circle: 2 times pi times radius or diameter times pi
How do you find circumference?
The formula is 2 times radius times pi or the diameter times pi. Circumference is 2r times pi. Assuming you are referring to a circle.
What is 12.8 times pi?
When you multiply 12.8 times pi the exact answer is12.8 Pi, but you can round off the answer to40.192because pi is about equal to 3.14.
