Multiply each of the fractions by 1 to get them to have the same denominator. 1/4 x 3/3 = 3/12 1/3 x 4/4 = 4/12 New Equation: 3/12a + 4/12a + 8 = 22 now add up similar terms 7/12a + 8 = 22 subtract 8 7/12a = 14 multiply each side by your denominator 12(7/12)a=12(14) 7a=168 divide by 7 a = 24
Distance around the round patio is circunference of a circle circumference=2 times radius times pi or diameter times pi so we have diameter=14 circumference=14 time pi answer is 14π
if you want to aprox pi to 3.14 then 14 times 3.14=43.96 meters
