Answer:

153.86 ft²

Step-by-step explanation:

Formula to find the area of a circle is :

Area = πr²

Here,

r ⇒ radius ⇒ 7 ft

Let us solve now.

A = π r²

   = 3.14 × 7 × 7

   = 21.98 × 7

   = 153.86 ft²

Given :

  • radius of circle = 7 feet
  • π = 3.14

[tex] \\ \\ [/tex]

To find :

  • Area of circle

[tex] \\ \\ [/tex]

We know :-

[tex] \bigstar \boxed{ \rm Area~of \: a~circle = \pi {r}^{2} }[/tex]

[tex] \\ \\ [/tex]

So:-

[tex] \dashrightarrow\sf Area~of \: a~circle = \pi {r}^{2} [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\sf Area~of \: a~circle = \pi \times {7}^{2} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\sf Area~of \: a~circle = \pi \times 7 \times 7 \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\sf Area~of \: a~circle = \pi \times 49 \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\sf Area~of \: a~circle = 3.14 \times 49 \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\bf Area~of \: a~circle = 153.86 {feet}^{2} \\ [/tex]
