Question

A circle has a radius of 5 ft. What is the area​

Answer 1

78.5 ft²

Explanation:

The area of a circle is given by

Area = πr²

where r is the radius = given as 5 ft

π = 3.14

substituting the values into the equation, we get

Area

= πr²

= (3.14) (5²)

= 78.5 ft²

Answer 2

Solution :

Here, we have given that the radius of circle is 5 ft.

So, finding the area of circle by substituting the values in the formula :

`\longrightarrow{\pmb{\frak{Area_((Circle)) = \pi{r}^(2) }}}`

`\longrightarrow{\frak{Area_((Circle)) = 3.14 * {(5)}^(2)}}`

`\longrightarrow{\frak{Area_((Circle)) = (314)/(100) * {(5 * 5)}}}`

`\longrightarrow{\frak{Area_((Circle)) = (314)/(100) * {(25)}}}`

`\longrightarrow{\frak{Area_((Circle)) = (314)/(100) * 25}}`

`\longrightarrow{\frak{Area_((Circle)) = (314 * 25)/(100)}}`

`\longrightarrow{\frak{Area_((Circle)) = (7850)/(100)}}`

`\longrightarrow{\frak{Area_((Circle)) = 78.50 \: {ft}^(2) }}`

`\star \: {\underline{\boxed{\sf{\purple{Area_((Circle)) = 78.50 \: {ft}^(2)}}}}}`

Hence, the area of circle is 70.50 ft².

`\rule{300}{1.5}`
