- Given - radius of circle equals 0.9 yards
- To find - circumference and area of the circle
We know that ,
[tex]\qquad\underline{ Area \: of \: circle\: = \: \pi \: r^{2}}[/tex]
[tex]\\\therefore \: area = \frac{22}{7} \times 0.9 \times 0.9 \\ \\ \implies \: area = \frac{17.82}{7} \\ \\ \implies \: area = 2.55 \: yards {}^{2} \: (approx.)[/tex]
also ,
[tex]\qquad\underline{Circumference \:of \: circle\:=\:2 \pi \: r}[/tex]
[tex]\\\therefore \: circumference = 2\pi \: r \\ \\ \implies \: circumference = 2 \times \frac{22}{7} \times 0.9 \\ \\ \implies \: circumference = \frac{39.6}{7} \\ \\ \implies \: circumference = 5.66 \: yards \: (approx.)[/tex]
hope helpful :)
