Answer:

a. 1385.44 ft²

Step-by-step explanation:

Area of a circle

• πr²

Given

• r = 21 ft

Solving

• 22/7 x 21 x 21
• 22 x 3 x 21
• 66 x 21
• 1386 ft²
• Option A is the closest answer

Answer 2

$\color{red}{ \tt{Given : }}$

$\textbf{ radius = 21 ft }$

$\color{red}{ \tt{Solution : }}$

$\textbf{Area of circle = πr²}$

$\bold{ = \frac{22}{\cancel{7}} × \cancel{21} × 21 }$

$\textbf{= 22 × 3 × 21 }$

$\textbf{= 1386 ft²}$

${\boxed{{area \: = 1386 ft²}}}$
