Question

The radius of a circle is 8 miles. What is the circle's area?​

Answer 1

`\huge\color{pink}\boxed{\colorbox{Black}{♔︎Answer♔︎}}`

200.96 miles²

Explanation:

`\textsf{\underline{\large{To find :-}}}`

The area of circle

`\textsf{\underline{\large{Given :-}}}`

radius of circle (r) = 8 miles

`\textsf{\underline{\underline{\huge{Solution :-}}}}`

`\sf \blue {Area \: of \: circle = \pi {r}^(2) }`

now we will substitute the value of r

`\sf \implies Area = \pi {8}^(2) \\ \\ \sf \implies Area = \pi * 8 * 8`

`\sf \pi = (22)/(7) \: or \: 3.14 \\ \sf here \: we \: will \: use \: \pi = 3.14`

`\sf \implies Area = 3.14 * 8 * 8 \\ \\ \sf \implies { \green{ Area = 200.96 \: {miles}^(2) }}`

Answer 2

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

• Given - radius of circle = 8 miles

• To calculate - area of circle

This can be easily calculated by substituting the value of radius in the formula of area ~

`Area \: = \pi \: r {}^(2) \\ \\ \implies \: (22)/(7) * 8 * 8 \\ \\ \implies \: (1408)/(7) \\ \\ \implies \: 201.14 \: miles {}^(2)`
