Question

Calculate the area and the circumference of the circle

Answer 1

A = 2.5434 C = 5.652

Explanation:

A = 0.9 times 0.9 times 3.14

C = 2 times 3.14 times 0.9

Answer 2

`\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}`

• 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.)`
