Question

The diameter of a circle is 28 inches what is the circle's area?

use 3.14 for pi

Answer 1

Answer:

615.75216....

Step-by-step explanation:

The formula is A = π * (ø/ 2)^2

A = Circle area

π = Pi = 3.14

ø = Circle diameter

A= 3.14  (28/2)^2

Answer 2

Answer:

Area = 615.44 inches

Step-by-step explanation:

Diameter = 2 * radius

28 = 2 * radius

Divide both sides of the equation by 2

14 = radius

Find area

A = π r²

A = 3.14 (14)²

A = 3.14 (196)

A = 615.44

Hope this helps :)
