Answer:

  • 314 in²

Solution:

Area of a circle is given bythe formula:

‎ㅤ‎ㅤ‎ㅤ➙ A = πr²

So, in a quarter circle we divide a circle into 4 parts, the area will be:

‎ㅤ‎ㅤ‎ㅤ➙ A = πr² / 4

Here,

  • Radius= 20 in
  • π = 3.14

Therefore, Area:

A = πr² / 4

A = ( 3.14 × 20² ) / 4

A = ( 3.14 × 400 ) / 4

A = 1256 / 4

A = 314 in²

Answer:


\huge\boxed{\sf 314 \ in.^2}

Explanation:

Given that:

Radius = 20 in.

Formula for area of a quarter circle:


\displaystyle = (\pi r^2)/(4)

Solution:


\displaystyle = ((3.14)(20)^2)/(4) \\\\= ((3.14)(400))/(4) \\\\= (3.14)(100)\\\\= 314 \ in.^2\\\\\rule[225]{225}{2}
