Question

The diameter of a circle is 36 inches. What is the circle's area?

Answer 1

Answer:

• 1,017.36 in²

Solution:

The area of the circle is the region occupied by it in the two dimensional plane.

Area of a circle is given by ;

• ➝ πr²

The diameter of the circle is 36inches

‎ㅤ‎ㅤ‎ㅤ➙ Radius = D / 2

‎ㅤ‎ㅤ‎ㅤ➙ Radius = 36 / 2

‎ㅤ‎ㅤ‎ㅤ➙ Radius = 18 inches

Therefore, area :

➝ A = πr²

➝ A = 3.14 × ( 18 )²

➝ A = 3.14 × 324

➝ A = 1017.36

Answer 2

Solution:

We know that:

• Diameter of circle = 36 in.
• Radius of circle = Diameter/2 in.
• Area of circle = πr²

Finding the radius of the circle:

• Radius of circle = Diameter/2 in.
• => Radius of circle = 36/2 in.
• => Radius of circle = 18 in.

Finding the area of the circle:

• Area of circle = πr²
• => Area of circle = (3.14)(18²)
• => Area of circle = (3.14)(324)
• => Area of circle = 3.14 x 324 = 1017.36 in²
