22/7=pi (roughly) 7 times pi is 21.99115 pi is 3.1415926535898 etc
7*pi/5 = 1.4*pi pi < 1.4*pi < 1.5*pi and so the angle is in the third quadrant.
A = (pi) * r^2 = (pi) * (7)^2 = 49*(pi)
It wasn't thought of. It's just "the answer". People thought of 22/7

Though pi lasts forever and cannot fully be written out, pi is commonly known for its first three numbers: 3.14 pi = about 22/7 pi = 3.1415926535897938.........and so on
22/7=pi (roughly) 7 times pi is 21.99115 pi is 3.1415926535898 etc
99,800 of them.
7*pi/5 = 1.4*pi pi < 1.4*pi < 1.5*pi and so the angle is in the third quadrant.
360o = 2*pi*radians or 180o = pi*radiansConvert 7*pi/15 radians to degrees1 radian = 180o/piTherefore: 7*pi/15 radians = 7*pi/15*180/pi = 84 degreesConvert 84 degrees to radians1o = pi/180 radianTherefore: 84o = 84*pi/180 radians = 7*pi/15 radians.Hint: pi always in radian and 180 always in degree. They are equivalents (not equal) to each other.To convert from radians into degree, first erase radian by dividing the given value by pi radian and then multiply the ratio got by 180 deg.Same way to convert from degree into radian, first erase degree by dividing the given value by 180 and then multiply the ratio got by pi radian.So interesting! Is it not?
pi = 22/7

The equivalent fraction for Pi is 22/7 or 31/7
Okay so you know that the area is equal to 7. So: A=7 the area for a circle is A= (pi)r2 where A is the area. so 7=(pi)r2 solve for r 7/(pi)=r2 sqrt (7/(pi))=r rationalize it [sqrt(7pi)]/(pi) if you double the radius you get the diameter. 2r=d d=2[sqrt(7pi)]/(pi)
