The formula for finding the area of a circle can be written in many ways. If the radius is given, the formula is A=πr², where A=area, π=22/7 or 3.14, and r is the radius. If the diameter is given, then the formula is A=1/4πd², where A is the area, π is 22/7 or 3.14 and d is the diameter Given that the diameter is 46 inches and π=22/7 or approximately 3.14, the formula we can use is A=1/4πd² where A=area, π is 22/7 and d is 46 A=1/4*22/7*46*46 A=16662.57 inches² (It is rounded to nearest hundredth)
