Answer:

1) 615.44 un²

2) 19.625 un²

Step-by-step explanation:

Hello!

Area of a circle: [tex]A = \pi r^2[/tex]

  • A = area
  • π = Pi (≈3.14)
  • r = radius

1)

We can plug in the value of the radius to solve for the area.

Calculate

  • [tex]A = \pi r^2[/tex]
  • [tex]A = (3.14)(14)^2[/tex]
  • [tex]A = 615.44[/tex]

The area is 615.44 un².

2)

Plug in the radius to solve for the area

Calculate

  • [tex]A = \pi r^2[/tex]
  • [tex]A = (3.14)(2.5)^2[/tex]
  • [tex]A = 19.625[/tex]

The area is 19.625 un².
