What is the circumference of a circle if the diameter is 45?
141.372 Circumference equals pi times the diameter: 45 x 3.1416 = 141.372 If you memorize the formula, it will serve you well.
What is the area of a circle if the diameter is 45 feet?
A=pi*radius2=pi*(diameter/2)2 A=pi*(45/2)2 = 1589.625 square feet if pi=3.14
Why is pi given the value of 22 over 7 and not 45?
22/7 is a very good approximation of pi (it's around 3.14159...). Pi is nowhere near 45, nor is it close to 22/45 .
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 the circumference of a circle with diameter of 45 centimeters?
It is: pi times 45 = 141.372 cm rounded to three decimal places
Does pi over 4 equal 45 degrees?
pi/4 radians = 45 degrees. 2pi radians = 360 degrees pi radians = 180 degrees pi/2 radians = 90 degrees pi/4 radians = 45 degrees pi/3 radians = 60 degrees. et seq.,

What is pi times pi divided by pi plus pi minus pi times pi?
the same as pi squared, which is 9.86960440109
What is a 45 degree angle in terms of pi?
1/4 pi to find the degree in terms of pi, divide the degree by 180 in this example, 45 / 180 = 1/4

How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
