What are the radius and circumference of a circle when 0.75 of its area covers 48 times pi square inches?
If 75% = 48*pi then 100% = 64*pi Radius = 8 inches Circumference = 16*pi inches
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 ratio of 100 pi?
It is 100*pi : 1 or approx 314.159:1
What is pi times pi equal?
pi^2
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)
What sis the formula for the circumference of a circle?
the formula for finding a circumference is pi * r2 or 3.14 times the radius squared SO if you had 20 as the diameter the radius would be 10 times 10 is 100 so an example wouldbe pi * 100=??
What are the radius and circumference of a circle when 0.75 of its area covers 48 times pi square inches?
If 75% = 48*pi then 100% = 64*pi Radius = 8 inches Circumference = 16*pi inches
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 the ratio of 100 pi?
It is 100*pi : 1 or approx 314.159:1
Why is circumference equal to 2 times Pi times r?
circumference=pi circumference=pi circumference=pi
What is pi times pi equal?
pi^2
What is the circumference of a 100 foot radius in terms of pi?
