Question

Find the area of the circle with the given radius or diameter. Use = 3.14.

d = 12

A =
56.52
113.04
452.16

Answer 1

hello :
the radius is : d/2 = 6
the area of the circle is : A =π×r×r=3.14×6×6 = 113.04

Answer 2

Area = 113.04 square units.

Explanation:

Given : Diameter = 12.

To find : Find the area of the circle.

Solution : We have given diameter = 12 .

Radius =
`(diameter)/(2)`.

Radius =
`(12)/(2)`.

Radius = 6 units.

Area of circle = pi * (radius)².

Area of circle = 3. 14 ( 6 )².

Area = 3. 14 * 36

Area = 113.04 square units.

Therefore, Area = 113.04 square units.
