  • Given - radius of circle equals 0.9 yards

  • To find - circumference and area of the circle

We know that ,


\qquad\underline{ Area \: of \: circle\: = \: \pi \: r^(2)}


\\\therefore \: area = (22)/(7) * 0.9 * 0.9 \\ \\ \implies \: area = (17.82)/(7) \\ \\ \implies \: area = 2.55 \: yards {}^(2) \: (approx.)

also ,


\qquad\underline{Circumference \:of \: circle\:=\:2 \pi \: r}


\\\therefore \: circumference = 2\pi \: r \\ \\ \implies \: circumference = 2 * (22)/(7) * 0.9 \\ \\ \implies \: circumference = (39.6)/(7) \\ \\ \implies \: circumference = 5.66 \: yards \: (approx.)

hope helpful :)
