The equivalent fraction for Pi is 22/7 or 31/7
The area of the full circle is (pi) R2 = 64 pi.We call a full circle "360 degrees".The 300-degree sector is (300/360) = 5/6 of the full circle, so its area is(5/6) x (64 pi) = 167.55 square units (rounded)
NO!!!!! pi is an irrational number, which means it cannot form a ratio/fraction. An approximation of 'pi' is the improper fraction '22/7'.
3.28 = (3 x 1) + (2/10) + (8/100)
17 : 12 ==========just factor out 25
the decimal form of pi is 3.14
Pi x 300 = 942.48 ft2
To convert revolutions per second to radians per second, you need to multiply by (2\pi) (since there are (2\pi) radians in one revolution). Therefore, if the motor makes 300 rev per second, the angular speed in radians per second would be (300 \times 2\pi = 600\pi) radians per second.
The simplest form of pi is 3.14. Hope this helps. ;D
The diameter = 2*radius. So the radius = 600/2 = 300. The area of a circle = Pi*r^2 = Pi*(300)^2 = 90000*Pi. For more information, you can visit the link mentioned below.
-- 4 pi -- (pi)2 -- e3 -- square root of 300
While there is no fraction form for pi, 22/7 is an approximation of pi that can be used for a rough calculation .

300 is already written in expanded form.
circumference = 4 pi, so arc is 4 pi x 75/360 = 300 pi /360 = 5 pi/6 = 2.62
Total surface area = (2*pi*r2)+(pi*r2) Area = 300*pi in square units
22/7 * * * * * Since pi is a transcendental number, which is a kind of irrational number, there is no fractional form of pi. 22/7 is merely a fractional approximation.
