Is 10 pi rational?
No 10*pi is not a rational number because it can't be expressed as a fraction
What is the volume of a cylinder with a radius of 4 inches and a height of 10 inches?
V=PIr2h =Pi(4)2(10) =Pi(16)(10) =Pi(160) about 502.4in3
What are the first 10 digits in pi?
The value of Pi is 3.14159, but the first 10 digits are 3.141592658
Circumference of a 10 inch circle?
If its diameter is 10 inches then its circumference is: diameter*pi If its radius is 10 inches then its circumference is: 2*pi*10
Why is 10 pi irrational?
A non-zero rational number (10) multiplied by an irrational number (pi) is always irrational.
What are 3 different ways to write pi?

How do you write cosine in terms of sine?
cos(x) = sin(pi/2-x) = -sin(x-pi/2)
How do you write pi?
Pi is approximately 3.1415
Define pi and write a history of pi?
a number
What are three ways you can write pi?
You could use the Greek letter, you could write "pi", or you could express it as the Gregory-Liebnitz series which the typography here will not allow me to reproduce, but it's basically the sum of the infinite series from i = 0 to infinity of 4 * -1^i / (2i+1).
What is the area of a sector of a circle that has a diameter of 10 inches if the length of the arc is 10 inches?
The area of the full circle is (pi R2) = (25 pi) square inches. The full circumference is (2 pi R) = (10 pi) inches. An arc length of 10 is [ 10/(10 pi) ] = ( 1 / pi ) of the full circle. So the area of the sector is (full area / pi) = (25 pi) / pi = 25 square inches
What is the circumference of a circle whose area is 10 pi?
Area = pi * r² ; and Circumference = pi * 2 * r. So Area = pi * 10 = pi * r². Divide both sides by pi:r² = 10 --> r = √10Circumference = pi * 2 * √10
What is the area of a circle who's radius is 10?
The area of a circle equals the radius multiplied by itself, multiplied by pi. Pi rounded to the nearest hundredth is 3.14. If the radius is 10, multiply 10 by 10 and then multiply by 3.14. The area is 314. (Don't forget to write the units correctly cm2 etc)

How many gallons of water in a 10 foot round pool 2.5 ft deep?
Assuming 10 feet is the diameter: volume of a cylinder is v=pi*r*r*d=pi*5*5*2.5=62.5*pi cubic feet ~ 196.3495 cubic feet If 10 is the circumference then: c=pi*d 10=pi*d 10/pi=d r=5/pi v=pi*r*r*d v=pi*(5/pi)*(5/pi)*2.5=pi*[62.5/(pi*pi)]=62.5/pi cubic feet ~ 19.894 cubic feet
What is the equivalent of pi?
Pi can be written 2 ways, possibly more. The two ways I know of are these: 3.14 (rounded version) & 22 --- (the fraction form which is hard to write on a computer or this fraction form of 22/7) 7The value of pi has never been determined because it is an irrational number but it's usually taken as 3.14 to two decimal places or as 22/7 as a fraction.
