What is the area of a circle with a diameter of 5 m? Use 3.14 for pi. Round to the nearest tenth. 7.9 m² 15.7 m² 19.6 m² 78.5 m²

Respuesta :

Answer:

[tex]A=19.6m^2[/tex]

Step-by-step explanation:

We are given a circle

diameter =5m

we know that

[tex]radius=\frac{diameter}{2}[/tex]

[tex]radius=\frac{5}{2}[/tex]

[tex]radius=2.5[/tex]

so, [tex]r=2.5[/tex]

now, we can use area formula

[tex]A=3.14(r)^2[/tex]

now, we can plug values

[tex]A=3.14(2.5)^2[/tex]

[tex]A=19.6349[/tex]

so,

[tex]A=19.6m^2[/tex]
